VAC Ban: CSGO, Ranked. I was bad at the game back in the day, but in one game, I was able to kill most enemies almost without getting any damage from them. Next thing I know, ban.

Normal Ban: Unturned. I was playing with some friends, laughing and joking. I climbed on a tent and was shot into the air, causing the game to think I was flying. Next thing I know, ban.
