I'm a little confused about the nature of copyrighted material on forums. I warn everyone not to do it, but sometimes people do it anyways. Am I liable for this, or are they? Of course I remove copyrighted material, but it stands to reason that as my forum grows something might slip by. Can I somehow limit my liability by posting a notice or something? Is there any legalese that magically transfers copyright suits to them? I also had a question about using Twitter, Facebook, etc. Let's say I or one of my users embeds a tweet, FB post, or youtube video; and it turns out that it has copyrighted information in it. Who's liable in that case? Is Twitter liable, the twitter user who tweeted it, or is everyone liable who embedded that tweet in their site? I can't really find any definitive answers to this. Thanks!
