There is a person that has taken 2 of my names Both {pDs}Qazster and {pDs} Qazster, he has also impersonated others that I have noticed, one is Sam Hall, and he didn't just take it for 1 second and not even play, he actually played and died once.
Of course he impersonated dragon too but he died twice no kills (Dragon fails)
here is the link to his page :

EDIT it says no time was played but how does he die twice but doesn't play for any amount of time?
