This is an interresting topic.Where do fan made games fit in?.Are they also violating certain copyright laws if it's a fan made game?.How strict are these laws exactly?.There's 1000's off mario , rockman etc clones out there and i don't see them being deleted from certain websites.
I also played a few world off warcraft fanmade games and videos and they don't get deleted or sued.Nor do certain people which has popular tv programs as thier signatures.I think one should read the legal info about a game or whatever first before making a fan made banner ,game etc.
