No matter which art site I post to, inevitably, there is some maroon who feels the need to comment with something along the lines of "Nice art. Too bad you ruined it with a watermark." Seriously? You know, saying that makes me think you're probably one of those repugnant, slacking, sleazy art thieves whining because you can't steal it.
Sorry, but I do sell my work. Having work stolen and available unmarked for free all over the Internet can actually cost an artist contracts. I've seen it happen to other artists before. I make little enough as it is, I can't afford to lose any to some stupid art scalper abusing my work without my permission.
So, sorry, you're just going to have to deal with the watermarks and I would appreciate it if you bloody well kept your mouth shut about them. I can't stand them, either! I would LOVE to be able to put HUGE versions of my art up without watermarks, but unless something miraculously eliminates every last art thief in the world forever, that just isn't going to happen. Thank the art thieves.
EDIT: I really get a giggle out of the fact that the majority of Deviants who have faved this stamp don't watermark their work.
Edit 2: An astounding number of people comment that they don't mark their work because they either don't think it's good enough to steal or not the kind of stuff that gets stolen. You should know that I've busted people selling the crayon art of children on Zazzle after scalping it from the Facebook or Photobucket accounts of the parents. You would be stunned at what will get stolen and, sometimes, illegally sold.
