this site doesn't give a damn about art theft

Follow up on my last journal...it's now been over two weeks since I first reported one of my drawings, a tattoo design commission, that had been posted here without permission or credit (in fact, I'm pretty sure the person posting it is trying to pass it off as his/her own art) -

I reported it a second time, last week, and I know as a fact that some other users have reported it as well.  But...surprise surprise...it's still there.  I've even tried contacting the person who posted it, but no responses whatsoever.

Thanks again, DA.  Seriously, should I even continue posting my art on a site that obviously couldn't care less about the rights of the artists who use it?  XP
