kill slavers and their slaves.
Do you know any good location for slavers and slaves near the hub?
nope. Klamath and Den.
Nope, you can neutralise a bad rep vy killing slavers near the den, pain in the ass to work off a -200 rep, it'll take 200 slaver kills.
their slaves count too, so if you enc two slavers and three slaves and kill em all you get +5.
as I said, you can only work off negative reputation by killing slavers, it's much, much harder to get positive reputation, after 2 months I've only gained 9 rep at the hub, all my other reps are negative, and -12000 on LA scavengers, love the easy smg loots, but my rep suffers, a lot...
