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.
