Although you might be right that SOME centralized mixers might be actual scams that don't actually mix their users' outputs, many of them also try to build a real mixing service to make their users' outputs untraceable after the mix, no?
I'm talking about a hypothetical mixing service that actually does everything right, which may also exist somewhere, no?
Yeah, that's exactly my point that proves o_e_l_e_o and BlackHatCoiner's goal is to scam users out of both their coins
AND their data. You can't possibly mistake these scammers for "Privacy Advocates" since the custodians they promote don't provide any privacy whatsoever, despite the option for these custodians to issue fully anonymous Chaumian Ecash.
