Your appeal has been reviewed and accepted.
This would be classified as a normal kill, you were attempting to get retribution from someone stealing your car and had no intention of mugging them. Server rules don't dictate that you will be PK'd every time you pull a gun on someone and die. If this was the case, anytime someone would pull a gun out and demand someone leave a property and they were killed we would need to pk them. This is not the case, this kill falls under normal killing rules and is within RP guides.
Your character has been reinstated and can be used again.
