Due to recent events with (another) exchange collapse from hack, and millions in stolen funds that must have got mixed already, I got this concern of mine. Should users who advertise mixing services feel confident in this place? According to our Privacy Policy - Variation, administrator might choose to share individuals' information, even without law enforcement involved.

Has it even happened, or does it seem probable to you, for some agency to request any kind of take down due to the advertisement of a service that might be one of the top targets of the authorities when it comes to bitcoin as we speak? As far as I can tell for ChipMixer, bitcointalk is the gateway. It's unlikely you happen to access it otherwise.
