Especially when the prize is free game credits for a game's in-game store items.
I recently entered the Cosmic Break fanart contest. I normally avoid these but with my favourite genres of mechs, cleavage and lolis i just had to enter. Plus $200 worth of in game creds and bragging rights to have it included as in game loading screens was a bonus incentive.
I'm quite fortunate that the art communities are active in these threads. I already had an entrant blatantly copy elements from my entry with his own subtle changes.

I already placed this particular entry and a second one here to provide proof it's my own *sigh*
Of course detractors and supporters came in droves and pretty much what's supposed to be a fun thread to appreciate fanart entries turned into an art inquisition. Seriously messed up...
So, what are your experiences/stories of entering these things?
