Unlawfulls need to do their job better and make place more scary for the traders in border worlds. That would make people flock to the Kusari, Liberty and Bretonia. NOT REINH.
Then, unlawfulls there need to do their job, primarly hogosha and FA.
Pirating all those traders there, KNF enforcing the embargo, and things going wild there!
Liberty is heavily pirated as well, those guys just need to get out of those bombers and get transports so when traders refuse to pay they still get their profits.
After that Bretonnia needs to cut off the Leeds route and leave it in for IN RP people.
Then people will fill up Reinhald.
When everyone is doing their job and sticking to the trade routes their ID shows, there's more chance of actually having some trades done in that desolate place beyond o7.
