On forums such as Stack Exchange, is it okay to &quot;plagiarize&quot; myself across other forums and vice versa? Sometimes when I've had questions, I've simultaneously asked them on other forums as well. For example, I may ask a question on christianforums.com, copy the same question, and paste it on hermenutics.stackexchange.com to get more perspectives, and vice versa. Also, I may copy an old answer I've given on one of the forums and then used it to answer a similar question from the other. So long as I'm the creator of a question or answer on a forum, am I generally allowed to copy and paste what I've written and use it across forums, or do most sites consider themselves the &quot;owners&quot; of what I post, forbidding me from copying and pasting what I wrote elsewhere?
See https://stackoverflow.com/legal/terms-of-service and https://law.stackexchange.com/help/licensing. As with most social media sites, your contribution of content does not transfer ownership of any copyright in the content; rather, you grant to the platform a non-exclusive license. Because the license is not exclusive, you can grant similar or different licenses to other parties, which generally happens when you post the same content on other sites. (Of course, you can only grant licenses when you own the copyright or have a license that allows you to grant a further license, so posting content created by others can be complicated; this seems to be beyond the scope of the question, though, so I mention it only in passing.) To answer with respect to a specific site, of course, you have to look at the site's terms of service.
Evaluating a potential copyright violation is very fact-intensive, so we don't have enough information to answer the question. Making a copy is generally going to be a copyright violation, but there's still going to be a lot of breathing room under the fair use doctrine. Again, we'd need more details to provide a useful answer, but you may be able to analyze the question yourself using the following information. Analysis of fair-use defenses looks at four questions, and the answers to the questions can tip the scales in favor of or against a finding of fair use: Does your kind of copying affect the market for the original? To what extent can your copy fulfill the demand for the original? What if there were widespread copying of the kind you're considering? The more potential there is for the copies to replace the original, the less likely it is to be fair use. This is the most important factor in the analysis. Why did you make the copy? If you made the copy for purposes of news reporting, criticism, or commentary, it's more likely to be fair use. If you made a copy just so you could watch again later whenever you feel like it, that's may still be fair use, but it is somewhat less likely. If you made a copy so you could sell it for profit, that's almost certainly not fair use. How much did you copy? Did you copy the whole thing, or did you copy only as much as you needed to achieve your purpose under Question 2? If you copy "too much" -- both in the raw amount and as a fraction of the whole work -- it's less likely to be fair use. What did you copy? Such works can be copyrighted but are not part of the Highly creative works, such as poems, music, and movies, are at the "core" of copyright principles. A fair use analysis will be more stringent in these cases than when copying a purely factual work, such as a phone book, biography, or list of statistics. This is the least important factor in the analysis. So take all of those and imagine the answer to each on a spectrum. If you see things generally tipping in the direction of fair use, that's a good indication that you're going to be safe. If you see things tipping in the other direction, you may want to reconsider. Again, these can be notoriously tricky questions. If you're dealing with a real situation, you should consult an attorney to get an answer specific to your situation.
In general, using content provided by another who incorrectly posted it under a permissive license, such as a CC license, does not grant a valid license from the real copyright holder. That is, if A writes some code (or a song, or creates an image, or whatever else), it is protected by copyright. If B then posts it to the web, with a statement that it is released under a particular license, without having obtained permission from A, then B's &quot;release&quot; is of no value, because B had no rights to grant. If C downloads and uses this content, relying on B's license, then A could take legal action against C. C would probably be considered (in the US) an &quot;innocent infringer&quot; which reduces the minimum statutory damage amount, but does not otherwise change C's legal position. A could, if it chose, bring suit and possibly obtain a judgement including some damages. But to return to the practical case of code posted on one of the SE sites. Given the comparatively short code sections usually posted, and that they do not usually form a complete working program, and given further the stated educational purpose of SE, it is likely that in US law such a posting would constitute fair use, and in the law of other countries fall under one or another exception to copyright. That is a general conclusion, the details would matter. I have not heard of a case similar to that suggested in the question. I find it unlikely that an SE poster would post copyright-protected code without permission, that is valuable enough to be worth an infringement suit, and substantial enough and having enough effect on th market for the original to be outside the protection of fair use. Such a situatiion is, of course, possible, even if unlikely. Note that a cease-and-desist letter is not a court order, and is really only a threat of court action. its only legal effect is to put the recipient on notice, so that continued infringement is not without awareness of the copyright claim. To have legal effect the claimant must actually bring an infringement suit, which is not without cost.
I'm not sure this would be a copyright violation. 17 USC 117 says: (a)Making of Additional Copy or Adaptation by Owner of Copy.—Notwithstanding the provisions of section 106, it is not an infringement for the owner of a copy of a computer program to make or authorize the making of another copy or adaptation of that computer program provided: (1) that such a new copy or adaptation is created as an essential step in the utilization of the computer program in conjunction with a machine and that it is used in no other manner... Due to the shutdown of the license server, it is impossible to use the program without an adaptation. It is therefore an "essential step in the utilization of the computer program", and not infringing, in my opinion.
That would be pretty much a classical case of copyright infringement. Drawing a thing from memory is copying just as much as drawing a thing with the original before you or xeroxing a thing. The degree of match between the original and your copy may vary depending on how good your memory is, but that doesn't matter, because copyright protection is not about "making exact replicas", it is about copying in any form.
They have copyright in their additional text, and possibly in things like their visual design choices (fonts, layout etc). They may also have introduced a few deliberate typos to detect any literal copies from their version (rather as mapmakers add a few imaginary features to their maps). None of this creates any rights to the original text. You are still free to produce your own copies of the original text. Just get it from some other source so you can be sure not to include anything of theirs.
From your question(s), as well as your various comments, I understand you to have two general inquiries: 1. Is there any infringement of copyright laws if you use things like the titles of books, games, apps, names, address (and any other number of things) which you will then put into datasets that will be licensed for proprietary commercial purposes? You may freely put titles, names of people, places or things into datasets without fear that you are infringing on copyright or any other laws. That is clear. Copyright law does not protect names, titles, short phrases or expressions. Even if a name, title, or short phrase is novel or distinctive it cannot be protected by copyright. So, there is no point in discussing the doctrine of fair use in this context, because Fair Use is a defense, or a legal safe harbor that is merely an exception to copyright infringement allowing people to use a copyrighted works under specific circumstances. As I understand your intended endeavor, you will not be infringing on any copyrights to the extent that you are merely using factual data, like names of copyrighted things for the purpose of creating a dataset or an application to help access it. This is why I say you need not concern yourself with the test for Fair Use with regard to this issue. The Copyright Office states clearly, despite what people may think, that there are no exclusive rights in brief combinations of words such as: • Names of products or services • Names of businesses, organizations, or groups (including the names of performing groups) • Pseudonyms of individuals (including pen or stage names) • Titles of works • Catchwords, catchphrases, mottoes, slogans, or short advertising expressions • Listings of ingredients, as in recipes, labels, or formulas. When a recipe or formula is accompanied by an explanation or directions, the text directions may be copyrightable, but the recipe or formula itself remains uncopyrightable. Hence, these things are not registrable under a copyright. While something may be potentially attached to or included in copyrighted material, is not in and of itself subject to the protections of these laws. If it (whatever it is) cannot be registered for a copyright, it is not copyrightable. Because copyright registration/notices have been optional since 1989, when the U.S. attached itself to the Berne Convention, whereby copyright protection is automatic as soon as a work is “fixed in a tangible medium of expression” (written down, recorded, painted, etc.) it’s protected. No notice is required. Registration only becomes required for litigation or enforcement purposes. But this is really extraneous to your inquiry anyway, as far as it applies to the actual data. When you get into copying whole databases for your purpose, that analysis is different. 2. You want to "scrub" the internet for information that you intend to put into your proprietary datasets and use for commercial purposes, some or most of which is already in a database or some organized form, and you want to know if there is some sort of copyright or duty owned to the person who originally databased the materials? Since ideas, procedures, principles, discoveries, and devices are all specifically excluded from copyright protection, if you want to compile this type of information from the internet for the purpose of creating datasets, or searchable databases, this is permissible. That said, there are protections for existing databases under copyright law, provided under the concept of a "compilation copyright". A compilation copyright protects the collection and creative assembling of data or other materials. Compilation copyrights protect the collection and assembling of data or other materials, such that databases are generally protected by copyright law as compilations. Under the Copyright Act, a compilation is defined as a "collection and assembling of preexisting materials or of data that are selected in such a way that the resulting work as a whole constitutes an original work of authorship." 17. U.S.C. § 101. The preexisting materials or data may be protected by copyright since the selections of materials and the form they take in an existing database may be original enough to be subject to a copyright. However, the data itself is merely information and is not protectable. The Copyright Act specifically states that the copyright in a compilation extends only to the compilation itself, and not to the underlying materials or data. 17 U.S.C. § 103(b). As a result, "compilation copyrights" can't be used to place protection upon those things that are otherwise not protectable. In the case of Feist Publications, Inc. v. Rural Telephone Service Company, Inc., the U.S. Supreme Court ruled that a compilation work such as a database must contain a minimum level of creativity in order to be protectable under the Copyright Act. Feist makes clear that even a copyright protected database does not hold the right to prevent an individual from extracting factual data from the database (so long as you're not copying the entire database as a whole). If you take an already compiled and copyrighted dataset in its entirety, you must obtain a license for its use. However, if you are merely amassing great amounts of data to then put into your own dataset, that you are free to do. The big issue will be (and you seem to realize this) where you will amass this data from. Some websites have specific licenses in place that say you cannot use or rework their content. However, many times these websites simply throw these license requirements out there for users to see, despite the fact that they may not be (and some would argue) are not enforceable. The courts have heard arguments that "contracts" (the end-user licenses) that protect databases and information on websites is beyond the protection available through copyright law should be "preempted" by the Copyright Act itself. The preemption argument goes like this: Federal law controlling something that is subject to interstate commerce or use, should be controlled by the federal laws. So,since the federal government has enacted the Copyright Act to govern any protections to any original works, states should be (arguably are) prohibited from having contradictory laws. Because of the ability of a federal statute to preempt state law, and the fact that the Copyright Act at 17 U.S.C. § 301 sets forth specific preemptions, no state may create rights that are equivalent to any of the exclusive rights provided under the Act. It is this concept of preemption that prevents copyright protection from varying depending upon the state where a work of authorship is created. Arguably, the same is true for the internet, and supposed contractual relationship created through licenses that dictates how non-copyrightable material may be used. In the case of ProCD, Incorporated v. Matthew Zeidenberg and Silken Mountain Web Services, Inc. the court examined whether an end-user of a CD ROM phone database was subject to the license, when they extracted a large portion of the database and made it available over the Internet. The database was almost the same as the type of data in the Feist case-The lower court rejected all copyright claims and found that the shrinkwrap license that controlled the end user's right to use the data was both unenforceable (as a shrink wrap license) and preempted by the Copyright Act. As a result, there was no relief available to the creator of the phone database and the end-user was free to extract the data and use it as he saw fit. However, on appeal this decision was reversed (7th circuit). The appellate court did acknowledge that the database (on the CD) was not original enough to be protected by copyright (finding no copyright infringement by the end-user); However, they did find the end-user was breach of contract, since the shrink-wrap license prohibited the end-user's conduct. What this tells us is that these licenses (on websites) may or may not be enforceable. While the 7th Circuit found a contract right pursuant to the license, despite the preemption argument, another appellate court that is more liberal may find otherwise. Also, this was a disk, not the internet, which is the "wild west" of information, largely unregulated and unlitigated as it pertains to the legality and enforceability of (some) regulations that do exist. License agreements for site use on the internet are everywhere. If you take a database from some site that has a license saying you cannot take their work and add to it, or whatever, and you do add it to other databases that are not licensed and then make your own dataset - chances are you are NOT going to be infringing on anyone's copyright. That said, you may be in breach of contract (the license) if they find out about it, and sue you (using it doesn't put you in breach; only getting sued and having a court determine you're in breach puts you in breach. It may be a distinction worth contemplation, but that is up to you). The safest, bet would be to get a license from them to rework the materials. If the material is generic enough, and will be changed enough, that you are creating your own new (copyrightable) work - I'm not sure how they would know you "scrubbed the data in contravention of their license agreement ( I have NO CLUE if there is coding or metadata attached to it such that it's identifiable in that way. I have not tech background and do not endorse taking what's not yours). But if they can and do know, they could cause problems for you. Lastly, I will just say that the internet is littered with sites that claim copyrights, or impose unenforceable licenses on material that is ripe for public use. Just because it says it's theirs does not make it so. The inverse is also true. Just because a site does not claim copyright to something, does not mean it is in the public domain. I would recommend either sticking to public domain/use sites for your scrubbing endeavors, or seeking permissions from the sites who impose licensing requirements. Short of that, I would recommend (as I already have) seeking an formal legal opinion to say that you are not imposing on anyone's copyrights (this could only be done once you showed an attorney every place you took material from, as well as what the material is), and that the licenses from sites with generalized information that may try to limit use, are unenforceable. I would do this before you invest a lot of time or money into something that is largely based on the accumulation of other peoples work product. I wish there was an answer certain, but there just isn't without seeing everything in the end.
The part about "If I'm the owner of the content, surely I have the right to request its deletion" is the problem. Sure, you have the right to request, but you can't legally compel. You have an agreement with them, according to which you got something, and they got something. You can't then take back the thing that you gave them, which is permission to use. You didn't give them the IP itself, which you still hold. Here's an analogy. You may own a car, and can give a person permission to use the car (let's say "if you bring me back a pound of cheese from the store"). You cannot later change your mind (especially after you've gotten the cheese) a say that you retract that permission and therefore they actually stole your car. When permission to use is given, as long as the conditions for granting permission are satisfied, you can't un-give permission.
