Or if the cap driver is unable to RP properly for long enuf (read: not just not following orders of the faction, but actual disruptive behavior) then take the cap.
Pirate caps also need restrictions on how hteyre used to keep the RP in check, for example there was a spyglass in Penn along with 2-3 other pirates, who were simply hunting down LN personel.
No real attempt at RP, just PvP whorage with a battleship to protect lolboats.
