' Wrote: a character who is properly affiliated as a member of a faction (matching ID and Tag), may not be prevented from purchasing ships or equipment from a system belonging to the same faction, regardless of whether or not that system is owned by a player faction. For example, the Hellfire Legion may not prevent properly affiliated Lane Hacker characters from purchasing ships or weapons from Vespucci.

None of these decisions prevent a player faction or non-player faction members of an npc faction from exerting influence (including gunfire) on characters belonging to their npc faction who are behaving contrary to the accepted roleplay for that faction as created by the mod and described by the Administration. In other words, if a Corsair affiliated character is behaving contrary to the way a Corsair should behave (for example, allying with BHG and attacking The Order) then other Corsairs may consider him hostile and act accordingly.

The point is that disruptive behavior may be dealt with by factions and players within the guidelines of their roleplay, but the simple fact of a ship purchase does not constitute disruptive behavior.
The corollary is that no one may be attacked simply for neglecting or refusing to post in a "registration" thread. If someone behaves badly, then their behavior may be influenced, but not posting in a "registration" thread is not bad behavior, nor is it mandatory according to the server rules, nor will player factions treat it as mandatory.
