Nobody follows those stupid rules here. They only exist for appearances and to satisfy potential advertisers and shit like that which doesn't matter right now, since there aren't any advertisers helping out. There is discussion about them being rewritten if you bother to read the site forums. I used to bitch about them too but I have realized that it doesn't matter so why bother. If something is really bugging you then report the image or comment and if they are sober enough and care enough about it they might do something. It has been known to happen but you've got to have a pretty good reason. I don't think copyright qualifies and I doubt that anyone is gonna bug these guys about that shit cuz no one is making any money from it, which is of course the bottom line for copyright infringement cases. The copyright holders are being credited so that part of the legality issue is satisfied.
