Alt + Tab = Ban? Help!

My Friend "-i[SL0]Fu(Ck)." (remove brackets around Ck, his name is inappropriate)was playing a game of S&D. He described to me what happened; I wasn't with him. He was on Facebook, telling a story to someone as he was the first to be dead. And of course he used Alt + Tab to use Facebook, while still in game. His story took a little longer than he expected and when he came back into the game, the game was about half way in the next round, he estimates. He said that he had a black screen for about 1 minute.

He was expecting a Client error, but this time, he got a hack tool pop-up. He didn't care for the time, so he tried to log in again, but he was actually banned for 2 weeks, the clan is confused and want him back on his main account.

He is Currently using the account "i[Brian]".

Brian was working for a namechanger through surveys, he accepts if his name is changed by a GM.
