I reported a user here who has been selling items as exclusive on AJ and you can easily find them on his author portfolios on other stock sites as well. I was told something would be done about it by an envato mod, went through the proper channels etc… was assured it was being looked into. Last I checked he’s still selling the same items here and on other market places.
I love the community here, I like the layout of AJ in general, and I’d seriously consider putting together an exclusive portfolio here if it weren’t for the fact that the general quality control, upkeep and enforcement is just plain awful.
