After a tournament in 2014 some kids thought me and a mate of mine were cheating and started hunting us down...
they managed to trick me onto their teamspeak server where i ended up downloading a virus resulting in them beeing able to take over my steam account. The first thing they did was using free cheats in mm so i got banned.
This was all proven and bans were removed from esl / esea and i was allowed to reenter the team with another account.
