If zkSNACKs get seized they'll have a good defence. They'll tell American govt regulators they're working with blockchain analysis companies to reduce frauds. Isn't it going to be ironic if they're forced to close Wasabi Wallet coinjoin services after they've taken steps to protect themselves by analysing who's coins were naughty?
Ironically since zkSNACKs coordinator has not implemented blacklisting yet, it could still get seized, or more likely forced to shut down, if hackers turn their attention to it next.
