I don't understand why you are being so aggressive. This is a post about news on laundering crypto. I am aware of a technology that seems to cater to that use case.
I would assume that it's because your comment reads like an advertisement, since it name-drops (and links to) a specific mixer rather than just saying "It seems that a coin mixer could have been used..." Is there anything novel about this particular mixer? If not, why link to this one specifically?
Talking about mixers (such as tornado_cash) is a worthy discussion on a post about laundering cryptocurrencies.
