The client states no spell-driven gain, and none of the 62 quests below has yet been shown as repeatable by its quest giver, so there is no rate to count per turn-in: the quests pay once each, and reputation from kills stays on the server.
How you earn it
No route sentence written yet. The 62 quests the server answered for are listed below with what each pays; reputation from kills and any turn-in's repeat rate live on the server and are added once confirmed in game or in Blizzard's footage, with the source beside them.
Rewards by standing
No item in this client is gated by a standing with this faction. Older clients mostly kept the standing requirement on the vendor rather than the item, so a quartermaster's stock does not show up here.
Quests that reward Bloodsail Buccaneers
62 quests the WoW Classic Era server answered for, read from the client's own quest cache, 62 of them a loss. The reputation per quest is the client's QuestFactionReward table at the index the server names, or the amount the server states outright in hundredths of a point (a Craftsman's Writ that states 7,500 paid 75 on the Forever beta); a loss the client names only through its second table says so instead of a number. "until" is the standing the cache says the reward stops at. Grouped by the zone the client sorts each quest under.
