And yes i'm a little angry about some fanart uploaded by me related with games when is near imposible to find any art and rejected.
This is of course only my opinion, but it's simply not "Fanart" if you just take an image and upload it 100% unaltered, no matter if it perfectly fits the theme of a game or not. And just slapping a clear logo from a game on it doesn't change anything.
This is not Fanart.
And yes, I personally would prefer no Fanart images rather than thematically fitting, but otherwise completely unrelated images. This is not a database of good looking wallpapers, but a database of games.
And regarding copyright:
It's easy for you to say that your contributions should be accepted if it's not your money that's on the line. Using pictures that are 1:1 lifted from the ESPN, Getty stock images, NY Times and other well known sources is playing with fire. All these sources regularly send cease and desist letters, sometimes including bills for their lawyers. Saying "but everybody else does it" is no excuse.
I would strongly advice you to read this text about copyright before you upload you next picture so you can make a better decision if the picture is indeed "Fair Use".
