Hello, I'm the admin who approved the PK. When joining a criminal faction all users understand and partake in the risk of being Permakilled as is the nature of being a criminal. Members of a faction who break their IC code of conduct or run risk to the faction can be ordered killed by the faction leader. you brought unwanted attention to the crime family you were a member of by stealing multiple oil barrels from the Rockefeller oil company as well as harming relations with another faction that was allied with your faction, and the faction leader placed orders for you to be killed.
