One things for sure, Black Widow was on a tear after Sleazy and perhaps some others as well.
Where as BF has always been really cool. There would have to be a major Dr Jekyll/Mr Hyde thing going on.
I kind of lean towards BF being framed.
Besides this person really had something against Sleazy esp and as you said Sleazy, you and BF never had probs. Seems a few others would be before you if BF went to the dark side.
OTOH BF has taken alot of shit, maybe he is waking up and webwalking in his sleep as Mr Hyde and unknowingly seeking revenge... Just saying.

j/k
I seriously doubt BF has 2 diff personalities. One who has given alot to this board and is a successful bizman and one who was really just a jerk and lasted about a week around here.
The dude aint no dummy and with 15 mins to edit, you really think he was using a proxy, posting, and in 15 mins not realizing it wouldn't be too smart to leave his icq out there as Black_Widow?
