Roleplaying on the behalf of other players or NPCs (if roleplaying for that NPC grants an advantage) is classified as powergaming. This includes roleplaying as a character that is not on your account without permission from an administrator. Roleplaying an NPC for the purposes of character development or immersion without granting any advantages, however, is permitted.

Other forms of powergaming include acting in ways that are physically impossible for your character, roleplaying retroactively, shooting while driving a vehicle or failing to indicate that you are drawing a large weapon. Weapons smaller than a sawn-off shotgun can be selected without additional description. Equipping all other weapons must be indicated via an emote.

Players cannot solely use the in game mechanics to steal another player's vehicle whilst said vehicle is occupied. The situation must be role-played out between both parties.

Examples:
You roleplay that you purchased a bomb from an NPC organization, and then use the “bomb” to destroy something.
When you are shot, you roleplay that an NPC called the police on your behalf.
You punch someone, and then inform them via a /me or /do message that they are unconscious.
You roleplay that you receive orders from an NPC to commit crimes, kill people, or other perform other actions.
You roleplay that you are carrying a weapon or item that can be obtained in-game that you do not actually possess.
When the police frisk your character down and find an illegal item, you explain via out-of-character chat that you hid it somewhere else in-character a while ago, and therefore it is no longer on your person.
As a policeman, you decide that you can see the weapons in a person’s vehicle without giving them a chance to indicate where they are, and you take action immediately.
You withdraw an assault rifle without indicating it in an emote beforehand.
You are in a pursuit with the LSPD and begin to fire at them to try to get them to back off.
