This happened earlier today, the thread has been moderated so if you missed it :
Explanation :
The guy apparently was pissed off he didn't get selected for the closed beta, so he decided to post a topic and insult the GM.
The thing is, he posted this topic in the Closed Beta forum. A forum that only the closed beta testers have access to, which means he's been selected but he's too dumb to realize it... Not sure if he was banned, but most likely.
