That the wabisabi coordinator is in the clearnet I think was a bad decision, although it has its technical advantages, it is horrendous for the protection of the coordinator operator and his anonymity.
Discussion
I wonder why an organization behind North Korea government would care to anonymize their UTXOS??
Looks conspiracy but, maybe all this is about to give US a reason to hunt more coinjoin coordinators after Samourai..
This is a good point
Why wouldn't they use joinmarket/jam?
It's a good question, I would say because the process a priori is more automated in wabisabi and joinmarket if you would make repeated coinjoins in joinmarket an attacker could link your coins with your network identity if you don't renew it constantly.
