I generally go by the rule "Fool me once shame on you, Fool me twice shame on me."
I will give the person the benefit of the doubt, until they attack, then I make a point of relentlessly hunting the ejit until they realise that they will die if they power their saber down.
However, often they complain about me killing them, because their saber is down!
As for notifying the admin, I am usually too adrenalised while playing to be arsed contacting anyone, so I prefer to settle it in game.
Nerf, it is hard to push someone with their back to the wall standing in an alcove
I dont use pull.
