Ok tez, now I'm back on the forum, I need to clear something up providing it hasn't been said already.
First of all, Regulith was at first asking him kindly what class he was.
Secondly, he kept saying either "5" or "3" and walking into walls repeatedly.
Regulith had no choice except to ban him. He wasn't answering at all.
So to me, I doubt he actually WAS foreign. I think he was just being an idiot.
