I think the real surfit's been around a few times in the last six months or so, most notably in the day or two after the 8-K came out.
But I believe that most of the time "surfit" is All*n. He's the one who considers Chris a rival, who's interested in felching, and who can't help saying "hehehe" all the time.
I don't think Surfit has been around for a long time. I think there are others trying to make it look like he is still around. I have no reason for my opinion, just a feeling.
