There seems to be some confusion over server rules regarding system camping.
My suggestion would be to add a server rule to the RP rules section, in order to clearly define what is and isn't allowed.
An idea for rule addition would be:
Players unfriendly to a faction may not log out while in the faction controlled system unless docked at the time.
As an example: The Junkers base in New Berlin would be available to players hostile to RM but not any of the lawful bases. Logging out while in open space could be considered a rule violation.
