Pretending? No ser, merely asking for fairness sake. We can assume that some of them are scams, OK, but ALL of them? I believe not. But if you could provide the verifiable data showing that all of them actually are scams that don't do the service that they claim, then that would be very useful, thank you very much.

Stop repeating this false claim,
you never provided proof that ANY of these scamming sites provide a service:False claim? Ser please, you stop with the gaslighting, I'm not even picking a fight with you. I merely asked if you have actual, verifiable data to show that those centralized mixers are actually NOT doing any coin-tumbling/mixing, which you replied that you don't have such data.
Plus relax ser, it's OK, I'm personally NOT saying that you're lying. I simply asked if you have the data.
