Let me make a clarification - it wasn't a swap, but a payout - at the time of writing, over 0.047BTC (some people made a bunch of BTC-ETH and BTC-XMR swaps).
After the debacle with Tumbler where I lost over 0.033BTC, I obviously wasn't happy with going through delays a second time.
Oh, I'm sorry, I didn't see earlier that it was about affiliate earnings. If it is the first withdrawal, they may have additional checks before approval, although I'm not sure why additional checks are needed because affiliate earning is calculated only after a successful transaction.
