If you're in mixer signature campaign, now you don't have to do anything. There is no need to show initiative. Mixer campaigns is allowed on Bitcointalk as long as theymos won't decide different. If one day he will decide to ban mixer campaigns, then you wouldn't have to make decision to leave campaign - all mixer campaigns simply would end then.
What theymos told to staff members is different story. Bitcointalk staff isn't same thing as regular members - they can be considered as employees of Bitcointalk. Emplyees of Bitcointalk advertising ''money laundering'' related stuff - it can bring problems for Bitcointalk. While regualr members can continue advertising basically everything, not just mixers, but also all kind of scams.
True, there is no need to panic right now. There will be an announcement if this forum would be banning the mixing campaigns so no need to speculate things too much.
I doubt, theymos will never ban these mixing campaigns. Also if you note that ever since the chip mixer campaign has ended, many new mixers have started advertising here.
Because it is not registered with a legal entity,
As for mixer services, basically it is impossible to get legality because serving "privacy" is not liked by the government. Then, any unregistered service will be inferred to be illegal and to contain "malicious" activity as is generally suspected.
and being registered means it's going to become centralized and there isn't going to be any privacy again; I don't know though, KYC may even be required before one can be allowed to mix,
If one need to do the KYC , then what is the purpose to the mixing of the coins.
One bad day, government will get all the KYC data from the mixers and then check who were involved in mixing the coins
