perhaps they appreciate the information about the kickout protocol even though it addresses something else
I talked with some folks about sybil resistance after making that post and it looks like the two main sybil resistance methods are:
- ensure every coinjoin costs a high fee so that sybils bankrupt themselves by joining it with multiple fake accounts
- make each coinjoiner prove they deposited 4x the coinjoin amount into a timelocked bitcoin address that they get back after a year, ensuring that sybils don't have enough money to make lots of fake accounts
Of the two models I think the first one is easier to implement (I can just increase the mining fee parameter) but I prefer the second option
