As far as I know there's no official announcement of no-KYC services being banned in this forum. But perhaps it's coming?
It was not allowed for having too many similarities with a mixing service, the non-kyc part was not the issue.
In addition they also offers a mixing service indirectly, even as they claims not to be a mixer, any service which offers to take your dirty coins and give you a clean one can also be considered a mixer which such is part of the service they offer.
By that logic pretty much any service that uses different inputs for withdrawals could be classified under the same category but ok, I understand that being promoted as a mixer is kinda too much.
