Probably you didn't meet him so much even when we were in Sky Clan, good for you i guess! When i used to play 5-6 hrs per day, i met him more then my mom in the house...
Rebel is the example of the retardness at its highest level! In his palmares you can count: drop on arrest, insults, teamnade, and so on. Talking by me, when i used to play in KGB server in the past i got forcespec-kick/ban by him a lot of times, for wrong reasons, like teamnade or kill arrest. Might be in my top three of assholes of SWAT, if i were to make one.
The reason why i put that line in the questionnaire is because i personally say NO to people like that in a team/clan/whatever it's called.
