Yeah, I know it's almost an impossibility for mixers to do that but some of them may want to introduce something similar to that to checkmate excesses so they can remain in business. It's just a hypothetical scenario I tried to capture there, anyway.
You have to think that at the same time that mixers require KYC from their users, the identities of the mixer owners would also be exposed to the authorities. And I'm sure no mixer will do something like that. It would make no sense to demand personal data from users and at the same time try to maintain the anonymity of the owners, since the second option would invalidate the first.
I believe a lot of users here will share that sentiment of yours too, giving the near panic we witnessed (as evident from the several threads created here to discuss that) when some of them were taken down by authorities two years ago.
That's right, I think it's the best, but it's just my opinion. What I don't understand is that there are still users wondering if it is possible for the mixers to return, when we all know that in one way or another that could damage the forum.
