The problem with people avoiding this coveted "corporate piracy" is that they want it both ways - harassing, robbing, and shooting their competitors without the possible RP consequence of that corporation's house wanting to protect their interests, just flying past that same faction's bases in their house space as if nothing happened.
If you're deathly afraid you'll maybe get a little red stain on your crisp green repsheet from shooting someone with connections, perhaps it's more a matter of hardening up and facing potential in-game consequences than seeking admin intervention to implement a broad restriction on RP distress calls and a response by law enforcement when that makes perfect sense as well. Not all house law enforcement chooses to pursue it, which is nice and can make for some underhanded fun when all parties consent, but when they don't consent, what were you expecting from robbing and killing people? It's a diplomatic risk that you've got to account for as a smart corporation with an image to maintain and relationships to foster in your cost-benefit analysis. Players criticize factions that are friendly/neutral to a majority of Sirius all the time despite their actions, so why are they trying to get the same treatment?
Get creative if it's too much for your delicate repsheet to handle: attack them by proxies and stir up more factions' activity, make keeping their mouth shut part of the demand, give kickbacks to corrupt cops, make your services to that house more vital than their own corps' in some way. There are countless possibilities. Also, if people were friendlier with each other OORP, they could come to better general agreements to piracy (without being too pitched and artificial) without anyone crying, but there are far too many egos invested in pixels.
