Can I grant and enforce specific conditions for the use of my copyrighted work? If someone contacts me asking for permission to share my original work on their website or Facebook page, am I within my legal rights to grant permission with specific conditions? For example, "You may post on Facebook if you include a tag link to my profile in the post caption." In the case of the example above, if they posted it without my profile in the caption (but perhaps in the comments somewhere), could I file a DCMA against them?
Yes and yes. This is what a copyright license is - the circumstances where you will give permission.
I do not have the phone number, email, or anything else associated with the account. Well, neither do I - so it must be my account. Unfortunately, the fact that you appear in most or all of the pictures on that account does not prove that you own it. It could be the photographer's account. Do I have ANY options here Can you reactivate the email account associated with the Twitter account? Or the phone number? Either would allow you to reset the password and access the account. You can go to court (in California) and seek an injunction ordering Twitter to delete the photos or give you access. Of course, you have the same issues proving ownership here as you did with Twitter but the court may have different priorities (justice) than Twitter does (corporate protection). I had an idea. If you (or your husband) own the copyright in the photos (i.e. one of you was the photographer) you could issue a DCMA take-down notice because the poster (who, according to Twitter, isn’t you) does not have permission (even if they did at the time: permission can be revoked). Twitter would be unable to contact the account holder and would be required to remove the images when they got no response.of course, if the photographer was someone else, they could do it. Or you could break the law and say it was you, although I would never recommend this even with a near zero chance of being caught.
Yes, you can do that, assuming that the pictures are really in the public domain (i.e. due to their age, and not only claimed to be). But you probably shouldn't, but you'll probably want to add a label to the images anyway (what it depicts, who the original painter is, etc). So adding a &quot;public domain&quot; tag to each image shouldn't be a big issue. You can do that on a separate page as well, giving the source for each. Note that while using pd images does not create a copyright violation, even if you blatantly say that you created them yourself, it could still be considered plagiarism. When writing a science book or even a thesis, this could get you into trouble.
If you do not have permission to make and distribute reproductions of the work, then it is illegal to make and distribute reproductions of the work. US copyright law Indian copyright law
The answer depends in part what venue you're talking about, e.g. Reddit, Facebook etc. The details are revealed somewhere in the Terms of Service for that venue. The general pattern is that you are allowed to use that venue, provides you grant permission for the service to do what they do with your content. You cannot legally send them a take-down notice for your stuff, because a take-down notice requires you to say that the stuff was posted without your permission (and that is false – and you can be punished for making that statement). There could be a venue where they do not hold you to an irrevocable license, in which case you could revoke that permission (but not Reddit: you granted them a "royalty-free, perpetual, irrevocable, non-exclusive, unrestricted, worldwide license to reproduce, prepare derivative works, distribute copies, perform, or publicly display your user content in any medium and for any purpose, including commercial purposes, and to authorize others to do so"). I've seen a site that actually asserts ownership of user-contributed content (I don't know if their TOS ended up being litigated) – if is not at all hard to write a TOS that includes transfer of copyright, rather than granting of a license. The only hard parts are (1) figuring out what you want in terms of permission to use and (2) whether your answer to (1) means nobody will use your service. SE and Reddit TOS probably are as close as you need to get for what you describe.
This seems to be a mix of question about law and a meta-question about this site, but I'll treat it as an on-topic question about law. The author of a question, or answer, owns the copyright to their contributions, and they can re-publish to their heart's content. Any user who posts here grants a license to SE and other users to use content posted here, so I don't have to ask you permission to quote you. As part of the permission granted by SE to use this website, you have agreed to &quot;follow the rules&quot; set by SE. There are many rules, some spelled out more clearly that others. For example, if you post a question, you indirectly agreed that your content can be upvoted or down-voted. Certain content can be &quot;closed&quot; and deleted, when the content is deemed to violate the rules in particular ways (is spam, porn, abuse, or judged to be poor-quality). Judgment (on different matters) can be rendered by community managers, moderators, or other users. The agreement is here, see especially here. If we take the post that you linked to, it is quite possible that it was deleted because it is not a general legal question, in violation of the acceptable use policy. If you want a historical analysis of your particular case, it should be asked on Law Meta.
In the US, at least, facts - like the speed of light, the name of a dinosaur or the moons of Jupiter - are not copyrightable. But the words or pictures, designs and original work used to express and present those facts in books, websites and other publications by individuals and publishers are copyrightable. (Original work doesn't need to be published to be copyrighted; it is copyrighted at the moment of creation.) See How can &quot;factual&quot; intellectual property be protected? Plagiarism can be copyright infringement; it's copying and presenting work of someone else's as your own. But not all copyright infringement is plagiarism in the sense that someone is claiming others' work as their own: if you're selling a T-shirt with an unlicensed design, you're not really claiming the design is yours; you're just trying to make money. If you use all or part of an image or a quote or a song from a copyrighted source in your own work, you need permission and attribute the source. Or, you have to decide if the amount of the copyrighted material you are using might be Fair Use and you don't need permission. But decisions on what might constitute Fair Use are ultimately decided in court, because that's where can you end up when a person or a publisher sues you for alleged copyright infringement.
Facts are not subject to copyright. Only a specific expression of a fact. When you describe a fact in your own words, then you are the sole copyright owner of that description, no matter who taught you that fact. But keep in mind that in the world of academia it is customary to always state your sources. But that's not a legal requirement. That's a topic for Academia Stack Exchange.
