I don't violate IP when i do not get any commercial interest from it. For first.
Second. I do not use any of official stuff, my art is exclusive and made by my own (are you seriously think tha my FAN art is violate any IP?)

If it uncomfortable for some reasons to right's holder he can only ask you to remove content that violates his rights, no more. There is no law that violates me from draw fan art. So think twice when you say something like that.

And for all top of things... how about Stargate:Redemption? How about fan-made Halflife, Mortal Kombat and other short films (can be found on youtube)? It is not violation until I do not take money for that and do not use official stuff.
