So, that's a thing of the past then? Why did you stop? You suggested a few posts above that I could run my own coordinator and outperform zkSNACKs by charging lower fees. Did that not work when you tried it?
I mean it's technically still running, I only used it for coordinating my own coinjoin one time.
Are you claiming they are the owners of the mixing services they advertise?

You do realize there is a difference between advertising something any owning a certain company or brand. So even if the thing they advertised was doing everything you said it does, it's not the people wearing the signatures that are stealing the coins or data. If the CEO of Nike was arrested for fraud, would you arrest everyone on the street wearing Nike sneakers for being criminals?
They are paid to promote custodians, it's not like they don't obviously know they are accepting fractionally reserved funds. And they have no excuse that they didn't see it coming because once the previous custodian finished taking all the money from their customers, they switched to advertise a new custodian. Can you guess what happened with the new custodian?
