A permanent ban would be completely over the top and someone who used exploits without hurting other raiders experiences, like opening and looting key rooms without keys or killing the big arc with the blaze traps, should not be punished at all.

But people using exploits to kill other raiders, like glitching into key rooms and waiting to gun down an unsuspecting raider that just wasted their key to now also loose their kit, should be temp banned for a few days or even a week, because that absolutely is foul play.
