Banned for modifying vehicle.

[Enzyme]

I cannot remember that I've said "It depends on if you make chaos in the city or not". This phrase sounds familiar but I don't see why I would say this about vehicle modification.

The rules on vehicle modification is clear:

Do not modify cars with props or tools without prior admin approval. Admins may modify a car with small objects/materials if it is required for an event.

As you said yourself; you had modified a vehicle without an admins permission.
