As a coinjoin coordinator, would you deny service to Sam Bankman Fried if he wanted to coinjoin stolen FTX funds? Or would you make his stolen coins private instead?
Hell, why stop there? If your blockchain analysis buddies don't want to provide services to SBF, then why not petition miners to blacklist his transactions altogether? There has been more than one mining pool in the past which has selectively censored transactions based on a blockchain analysis blacklist, OFAC blacklist, or other such bullshit. Only approved people should be allowed to use bitcoin at all! Congrats, you've just invented a CBDC.
After all, if you've got nothing to hide, you've got nothing to fear, right? Everyone who doesn't comply is a target.
You can fuck right off with your malignant permissioned privacy bullshit.
