I'm going to give you the benefit of the doubt and reduce your ban to 2 days. Eventhough you are apologetic, you still decided to fight fire with fire, (a rule breaker by breaking the rules yourself) (according to your story) I also want to add that if you drive fast with a vehicel and your game freezes, that it's still on the drivers responsibility most of the times if you run people over. Next time file in a report using "@" in-game with a clip so we can assist you instead of you handling scenarios yourself, shutting off your pc or game right after you killed someone is highly not advised neither, i'd suggest you to wait 10 minutes at least and then turn off the game so it can't be really considered Leaving to avoid Punishment
Your ban appeal has been reviewed and accepted.
The ban will be reduced to 2 days.
