OK. This is the closest to what I expected as an answer.
Two of these sites are not working, so I will delete them soon. Although I will probably leave UniJoin in the list only by removing the "CoinJoin" postscript (since this site has many clones, and despite the fact that it is closed, users should know which site was the original). I have not tested Whirto (and I have no desire to test it since I sent them a number of questions and did not receive a single answer, so their hashtag will return as soon as they prove otherwise). I have not tested Mixero, but as far as I can judge, they have been working for a long time without complaints. Therefore, I need a volunteer who could show a letter of guarantee and a successful transaction, and we could take a look to determine how similar their method is to CoinJoin.
@icopress, I see that [banned mixer] is offline in the monitoring, I just checked the site is available and seems to be functional. I don't know if this is entered manually or if some script automatically checks it.
It seems to me that there is a slightly higher level of CF protection, it is possible that this is the reason why the check shows that the site is unavailable.
You can see icopress is promoting custodial sites "Whirto", "Tengri", "Mixero" and "Unijoin" as coinjoin services. Now everyone who sends their money there will assume coinjoins are scams because they got their money stolen by yet another "mixing site".
Mixero is certainly not a phishing site, it is quite proven and there are no complaints about it. By the way, they recently implemented a new method, they named a ricochet, which in some further analyses is closer to coinjoin than to the classic mixer.
