A option of this might be to put weapons platform that they look like BS (the 2 osiris in omicron 100 that are guarding the order shipyard) near gates with incredible firepower so when you jump as "red" you will be obliterated forceing you to use jump holes instead
Seeing RM / BDM / Spyglasses / Outcasts / HF with BS / AGS / or any other factions that got bored of there zoi in front of 'hatten seems a bit oorp. Sure now go and put all the hate on me but we all know that Manhatten it's the capital of Liberty and it's pretty much guarded and those raids are actualy null.
People like to fly there RM magic sticks in NY but they whine alot when LNS capspam comes and they can't do a thing to them. For me it's pretty much what you should deserve when you'r attacking Liberty's territory.
It's a game we don't need the NPCs to do the job.
In any other words get used to it or move somewhere else when they'r there. Disco got boring due to not too many RP updates and people are starting to create there own ID / RP with different IDs.
And have alot of fun that's what's all about till you get sanctioned
