The Hellfire Legion/Lane Hacker situation is.... problematic at the moment, but we're working on getting it fixed up for the next version.
At the moment, I suppose you can consider the Hellfire Legion responsible for the Lane Hacker Guard group and all Guard bases, and the LH Lane Hackers responsible for the regular Lane Hackers group and bases.
Bumping either down to an unofficial faction, though, would make more than a few people very, very unhappy. Both are rather old factions.
