Anthere--
I think you should try not to take it personally. I suspect what may be
going on is the BFB is editing aggressively, not maliciously. He goes in and
edits what other people have been working on, I suspect, mainly because it's
what's on the Recent Changes pages. Because he makes so many, such
aggressive edits, it can be very frustrating.
The real question is whether a discussion, say, on his talk page, can allow
everyone to come to some sort of understanding.
He does have a nasty predilection for deleting content as he makes these
very strong edits.
But I suspect (hope) he's not trying to attack you. What I don't know is
whether he cares at all that he's effectively attacked you. I hope he would
care, if it's brought to his attention.
