There was also the time where people got banned in the Watch Dogs PC performance thread because they were playing a pirated copy before release. The thing is, the only reason the mods knew was because they demanded everyone who was posting to show them a receipt after they put 2 and 2 together.
I'll admit to laughing initially, but honestly, what business is it of yours how they got it, legally or illegally, as long as people arent posting links or saying where they downloaded it from?
