How many pages back did you quote this from to let people know it was 'stolen'?
I think its assumed that a majority of pictures posted aren't taken by said poster. People post shit on PUBLIC forums/blogs. Flicks get recycled. No need to mention its not your picture, this isn't a fucking research paper with cited sources.
If you don't want other people having access to your shit and re-posting it, keep that shit in your private stock. But don't act butt-hurt when someone else posts one of your flicks, which was probably stolen by someone else, who stole it from someone else, to the point where no one knows or gives a fuck who took the original. Just my .02. /EndRant
Here's some 'stolen' flicks for all that talk (don't know who originally took them nor do I give a fuck).
