Oh great... you chose one of the harder factions to get to like you -_-
Well, if you want a Freelancer tag, I've learned that killing Bounty Hunters makes your Freelancer rep go down, so I assume the opposite works too. In other words, do lots and lots of missions for the Bounty Hunters; maybe getting a Zoner bribe could help with the rep too, but I'm not sure about that. Anyways, when you're full rep with the Freelancers, start accepting and immediately aborting missions from the BHG so that you lose their tag. Hopefully, if no other factions are fully maxed out in friendly, you'll get the FL tag. Good luck with that:)
THEY TOLD ME I COULD BE ANYTHING SO I BECAME A SIGNATURE PLS HLP
Getting a Freelancer tag is damned hard. Expect to spend a good portion of time working for it if you want it. I would recommend staying tagless, but if you want it, you'll need to do some serious work. Double bribe the Zoners, then do BH missions 'till your rep for the Zoners drops waaay down. Then double bribe the Zoners again. Rinse and repeat. 'least, I think that's how it's done.
