-killing Xenon in Zyarth's Dominion would be awesome, if you could avoid RRF, but becouse of those Raptor and Vipers it's nearly impossible,
-the most effective way I found was killing Boron in Split sectors: Wretched Skies and Thuruk's Beard, pirates will do to if you don't care about their rep and can find them,
-traders which deployed drones were most helpful, since thanks to them you could repair around 7 or 8% of that lowest rank 'at once', while single ships seemed to give 1,5%, which still was important too,
-obiously I had to go back to Boron from time to time and repair rep with them; I did it every time when my rank with them fell to Noble Peer,
-once you get out of that lowest rank and become Enemy of Rhonkar (instead of Enemy of All Families) you can start doing missions for split on foreign races stations. I had most luck when searching for those in NE map corner, Hilla's Joy and stuff. You can do easy missions, but single hard or very hard mission should jump you to level 0 (Split Creature 50%).
-once you can enter their core sectors you still have to go around and do some apologising, since some entities will remain enemy:
--ships: comm them and say sorry, try again if it doesn't work at first try; some pilots are stubborn, but shooting down an M4 shouldn't be that much of a problem now,
--stations: unfortunately you'll have to hack them, altough there shouldn't be to many of them and it should be cheap,
--lasertowers: should switch automatically once you leave a sector where you found them, but if they don't, there is a problem, since shooting them may turn a station against you. Luckily, you already know how to deal with station
