Yes. Used to be a case where discussing the general status of cabal wars it was obvious as to who was the cause of things. These also tended to be named players repeating the same ability.
Case in point, (without ass kissing) I'd consider Abernyte to one of those players. He's got the patience to coral muppets and generally the self motivation to care.

It tends to depend on the characters around you, do they respond to you or do they take it personally.
