Why hasn't anyone started a class action lawsuit?
Newgrounds, Something Awful, Albino Blacksheep(which was a moderated term in the Ebaum forums), Weebls Stuff, YTMND, Camp Chaos. All these sites have had material that was legally submitted to them pop up on Bauman's site without proper permission.
Technically, Bauman doesn't steal them himself, at least from what I gather. He has other people that will take someone else's hard work, claim it as their own, and then submit it to the site for a one time cash payment, all done behind the scenes so the public doesn't know who is actually submitting it.
For whatever reason, Bauman thinks this setup makes him teflon coated, as he didn't actually steal anything, he is now just an overly trusting character, subject to the honor code. However, if the people that have been wronged were actually so inclined, depending on the local specific legalities of intellectual property theft, they could ostensibly all get together and file a class action lawsuit to have a) their original work removed, and b) fair monetary reparations based on the estimated value of how much advertising income those works brought into the site(a good lawyer could probably get the group 100% of that estimate).
If he were better/more ethical at doing his research, and/or actually would have responded to requests to have illegal submissions removed, then he could have avoided leaving this opportunity wide open. I hope someone's getting ready to take advantage of it.
