Virtus has been causing problems for a long time now. Unfortunately I haven't gotten any demos of his abuse. But he always seems to fuck with people when they get on or close to nade level.
(1) A couple weeks ago, on mario_reloaded, he started randomly blinding everyone (well, partially blinding). My monitor is kinda old so its a little darker, i was completely blind. I was on knife level, yet i got knifed and then naded all because I couldn't see.
(2) On complex, I saw him switch his team when turtles threw a nade at him... This caused him to be on turtles team. He then slayed turtles for the "team kill"
(3) Just now on pink panther... 3 people were on nade level and he slapped everyone down to 1 hp.
