Not sure why this even came back up, but like I said the lawful factions aren't expecting the Junkers to FR5 every unlawful getting caught docking at a Junker base just that they do some RP to discourage it from continuing to happen and if a group or player does continue to do so after the Junkers tell them off then the possibility of an FR5 against the unlawful that is abusing the Junkers hospitality. Also, like I said before the Junkers inRP should not be happy about about some random OC battleship or Rogue Scylla bringing heat down on their stations so they themselves should already be invested in preventing it from happening inRP.
Yes the Junkers are considered a necessary evil by Lawfuls but that is because they try hard to keep a good balance between helping both lawfuls and unlawfuls and keeping both from getting too annoyed by them not because of some "lore armor". This is just an example of the diplomacy RP that every other faction needs to do as well and is not exclusive to Junkers.
