ELI5:How does Snapchat not get in trouble for hosting child porn on their servers?
gpt
There's a law that exempts companies that allow users to upload content from being liable for the content they host that is uploaded by users. So if someone sends a snapchat containing illegal images, Snapchat isn't liable for hosting the image since they don't check individual images. If they discovered something illegal, they would probably be required to remove and/or report it though. 

This is the same for Youtube, for example. You can upload child porn to Youtube, but it will likely get removed when it's discovered and you'll get arrested. However, you can't call the cops before it's discovered and get Youtube in trouble for hosting it because Youtube had no idea they were hosting it.
