I like adding my pirated games on steam for the overlay and so my friends know why I might not be responding to them when I'm playing those games. But for some reason, when running a pirated Skyrim on steam and using the overlay, the overlay was displayed as if the Skyrim copy I had was legitimate, in that it featured the community guides and achievements. I immediately backed the fuck up and closed Skyrim, and I close steam whenever playing Skyrim now. Its been like a month and Steam didn't ban my account or anything, but any ideas for how this happened? I'm completely mindblown.
