They might have check't you're chat logs then. You probably got reported for a comment like that so. Anything you say or do in-game is logged.
And sometimes it can be hard to see the (ironic) side of a text on the internet's.
Hehe, yeah I know, and I shouldnt have made that comment, but it was bleeding obevious that it was ironic. But I'll just wait and see, I'm sure it should be no problem to get it unbanned it's just inconvenient
