(sic) Assuming that SlowMist DID trace those transactions, then that probably means that other user transactions that used CoinJoin could probably be traced too, no?
I assume that SlowMist did not trace anything because otherwise they would have used that case to prove the entire world how good they are with a detailed article, blog post, video or any other ways to bust their reputation. Instead the wrote: "Case of study #2 - Tracing Wasabi coinjoins: we did it, believe us. That's all, folks"
OK that's another discussion for another topic, and the main question still is hanging. - Can the Lighting Network provide an extra layer of privacy as a safety measure for users "in case" their CoinJoins can be traced?
I'm merely asking that question ser. I'm not forcing an issue whether SlowMist truly traced those transactions. That's for them to show the data for everyone to verify. No data, then it would be safe to assume that they didn't trace it, like you posted.
