@Quiron- No, but as the official faction, Phoenix was in a position to make a decision to allow an indie group of Zoners to build a PoB in their Guard system AT the jumphole.
I would certainly hold BAF responsible of they allowed an indie BAF group to build a hostile base at the jump hole in Salisbury.
This is why LN and BAF have application processes for PoBs, otherwise they attack them fervently to prevent this kind of abuse. It amazes me that they managed to let the Mollys get away with building Coin, but I'm not gonna blame the Mollys for that. Kudos to them.
