Whatever coins you try to coinjoin, Wasabi pays Coinfirm to spy on those inputs and decide whether or not they are "naughty".

We don't know, and Wasabi won't tell us. I suspect Kruw doesn't know this either - the knowledge is probably limited to the top 2 or 3 devs at Wasabi. But given that all blockchain analysis companies only exist to gather data and then sell and share that data with third parties, I would be very surprised if Coinfirm don't use this data that Wasabi pay them to gather in a variety of other nefarious ways.
