Someone took your car Ramis, it was not locked. So that makes it stealing.. What do you do when someone steals your car? Right.. You call the police. What you did is trying to take the car back by force. And by force I mean carjacking, deathmatching and flaming through /pm.
Here is some of that used langauge, under the spoiler.

You tried to trick the person with money, to get the car back. Which also you didnt give.

Why did you do it? Because you know all these actions you did was against the rules. You have a passport so I assume you know the rules.
