Yep, as the attacker you bias the entire playing field to your side. If a mailing list has 20 or so users on it, you create 50 accounts over time that are nice, helpful, and set a good tone. Then later you come in with your attack and the pushy assholes. Suddenly those 50 puppets just slightly side with the asshole. Most people break under that kind of social pressure and cave to the jerks request.
