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.

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.
