The base has been found indeed, and evidence of said finding has been withheld for now, lest he wants anyone to bring a Cruiser or a Battleship to pound it down before replying to the KSP...
Nah.
Hey guy who found it: You can blow it up if you want. I've already evacuated it of anything worth salvaging (and the Fleet Admrials, Cruiser Commanders, Gunboat Captains, Pilots, and other spoils of NPC piracy)
You guys need to get on the ball. It would normally take around half as long to find it.
And here I was hoping this was something about inactivity in Kusari, or "unfair taxes". In the end, it was just about checking if people still cared to follow rules and conventions in houses.
I was hoping you would still follow it up with some rp excuse or justification, but it seems it was just a pob to make a nuisance.
I suggest you try the Taus or some off house system. Less rules, and less roleplay hassle for your manufacturing needs.
