The new hive format and stingtalk are not set up for bulldogs liking. Meaning he can't start threads and overtake the board. He was getting a kick out of going over to the rivals boards and dominating discussion.
That's my theory, and I'm sticking with it.
Yes, bulldog can be a nice guy on the board and in person, having met him, but truly believe that was what his motive was/is.
