It would be very simple to build such a thing if you could analyze everyone's payments. With total surveillance, you can have total safety! Why would you want privacy when you could have safety instead?

The ironic part is that the government already tracks all payments everywhere in realtime and ingests them into a huge database. They could provide such a threat intelligence feed but that would tip their hand and remind the public that they have precisely zero financial privacy even if they're not suspected of a crime.

I suspect there is some /sarcasm in the parent post, the “techies” have already shipped crypto public ledgers which these scam sites use to steal their victim’s funds. Can it be sufficiently de-anonymised to do this analysis?
