Honestly if this led to any kind of massive faction abuse, I'm pretty sure the admins would step in and stop the whole thing. Plus from what I saw, there's multiple pages of rp posts related to it, so if you really wanted to stop it you could have done it a long time ago.
"The freighters of the Interspace Neuralnet Division will be welcome in our home system as long as they respect our laws. They are authorized to dock on Minato, Sarawak and Sulawesi."
