Part 2: PreMix, PostMix Stages

Further clarification:

Some Whirlpool coinjoins typically select 2 fresh inputs from Tx0s and 3 already mixed inputs from previous coinjoins
The fresh inputs from Tx0 are responsible for paying the fees.
Inputs that have been previously mixed receive unlimited free remixes.
Example (check the link): Two fresh inputs are 0.05014520 BTC; the other inputs are exactly 0.05 BTC.

Since Samourai collected the coordinator fee in the premix transaction, they managed to rug pull the users waiting in the premix queue when their coordinator went down.
