Won't miss it in the slightest.
It was trivially easy (but boring as hell) for someone to haul a bunch of UA's and shut down a station. Fixing a broken station was a complete pain in the and you either relogged at a barnacle over and over or you hoped nobody else was buying out Darnielle's Progress. It was a battle of "who can do this boring thing most".
As far as being a tool of BGS warfare, it was laughably one-sided as well. Some government types auto-close black markets so those guys were totally immune to the "tactic".
I remember hauling part of tens of thousands of MAs to Harma (a PP HQ) to fix it.
