I found this guy on Fotolia http://us.fotolia.com/p/203970210 [nofollow]
He stealing others illustrations, including my, and creates his own.

PS: Sorry for my bad English 

I just found this guy on canstockphoto! http://www.canstockphoto.com/bernmass/
He stole at least one of my friends and put it in his as if he created it.

His account is gone on CanStockPhoto

No reply from Fotolia yet, and he constantly adding more and more stolen content..
I was wondering when this will be solved

Fotolia dont care about copyright issues. I once was told in their forum by their forum moderator that I couldnt use elements of NASA images, and that I better delete all my images before getting into trouble, yet their library is full of it. I reported it, they said they would look into it, but nothing was done about it.
