I need to spill my guts out!

Well, unfortunately there are indeed enough people who publish games with stolen assets. Sometimes it gets into press, as case of Orion game and Activision. The question is why wouldn’t they? We have plenty of people who publish on steam, do any of them were contacted and asked for prove of valid license?
There are about 20-30 games published on steam daily, you have to screw it up really bad for anyone to remember your name.
