Griefers, but not very good ones; even when they have a squadmate over on the other giving the position and alt away of their intended victims, they still fail.
TC had that high 190 buddy of his vectored in on my position every time until he logged. Mr 190 didn't get anything during that bout of attempted greifing. You see TCs mechanics are old outdated and well known.
I think it's time they gave up trying to assert themselves and just got on enjoying the game, perhaps learning some more ACM along the way.
