I think 1. was clever because it used the good ol' post-delete method. Also in 1. the three members decided to work together without any communication behind the scenes. Also i think it was good coz the "target" got "mad bro"
I think 2 was just bashing some dumb guy which is kinda slack, and it was so direct and un-innovative. It looked more like "the troll" was mad bro and the other guy just deleted him for being stupid rather than "the troll" invoking anger in a witty/intelligent manner.
