I think it was RIVAL. Reason I think that is because in the topic where Bobby went on a rampage about Japan with the comedians beating up the korean MMA woman, RIVAL warned him about starting a flame war and maybe Bobby negged his post and got a return neg.
It's stunning.....it wasn't too long ago Bobby was being nominated for nicest member and I think was one or two votes from winning.
He is an MMA fighter now right? Maybe hes taken a bit too many punches to the head and has gone crazy?
The only thing else I can think of is maybe Bobby couldn't take Lyoto getting knocked out then losing a fight right after to Rampage pushed him over the edge.
