Bloodsail Buccaneers & Steamwheedle

Ok,
I know it is or was possible. I've seen enofe information about it with even a player back in wotlk world first doing this insane grind. Google doesnt want to help me because I only get information after patch 4.0.1

So my question:
What was the exact way to gain Bloodsail Buccanneers to Revered 20999/21000 (After that with a quest to exalted). AND then get you're steamwheedle back to exalted WITHOUT losing the reputation of Bloodsail.

I know it is possible and it was a grind for weeks because of the spawn time of an npc in badlands. I just dont know what npc. What the exact steps are.

So does anybody know where I find this information or does know it himself.

Wotlk ! So only things possible in 3.3.5a
