>A libel suit can be made as well as a copyright infringement suit.

All right if that's the case, who would the suit be made against? 4chan? Is the website really responsible for the for the actions of it's users to such a degree, after all if the users were doing something illegal on the site, the site rules forbid that, the most they could do is attempt to ban those posting the offending content. Are they going to attempt to sue the users of /pol/? Considering that's there's so many users contributing to this whole Ben Garrison debacle it'd be impossible to come up with a list of IP's of who to bring to court, then there's the issue of proxies, and the fact that anons may have multiple persons using the IP address which would make arrests so difficult no court on Earth would bother to take the case.Oh I should mention that I'm not the same guy you were arguing with, and I don't particularly disagree with you conclusion that a fair use defense might not stick.
