It was just stupid shit. We were in the shoutbox and he was going on and on about some other forum. Wouldn't stop posting stupid stuff, cutting off people's convos with stupid shit. I told him to stop spamming in the SB or I would kick him out of it. He didn't listen, so I banned him from the SB.
I have no desire to ban him from the forum, although he created a thread requesting to be banned...lol. I have no problem with him, and was actually one of the people who left him alone. However, he just caught me in a shitty mood this morning and this happened. No big deal.
