Wouldn’t a cryptographic sig suffice for this? You don’t need an authority vouching for you to become a ‘trusted’ criminal. You just need proof of identity, and a reputation established over time. Drug dealers do this all the time, even though they’re criminals. Hell, it’s even how legitimate businesses work - the FBI isn’t going to shut down Bic for selling shoddy pens, so they build a reputation on “we’re Bic and we did right by you last time”. An example: a malware group sends every target an RSA-signed demand (with public key disclosed on Pastebin or something). The few people who pay up find that they follow through, so they grow a reputation as sincere. They could even kick things off with a round of freebies - “Here’s your data, here’s our sig, we deleted/unlocked/whatever it for free this time to prove ourselves.” I suppose they’d have to publish demands and outcomes since most targets won’t disclose on their own. There’s likely a flaw in my specifics (probably around disclosing attacks and proving followthrough), but I only put five minutes into it. As long as you can prove identity, you ought to be able to build ‘trust’. |

Drug dealers and those buying from them are both committing illegal acts. That changes the dynamic. Neither party can rely on the legal system to enforce misconduct. That allows an entirely criminal system to work. For example, if you don't pay the drug dealer, they'll just hurt you. If the drug dealer doesn't give you the drugs, or gives you crappy/cut drugs, you just won't use them next time. It's important to note that this transactional relationship does not begin with one party accosting the other, as in the ransomware case.
The ransomware scenario is the equivalent of being mugged in an alleyway, but only of your smartphone, and the mugger offering to give your phone back if you go to an ATM and come back with $100. The whole interaction began with an crime perpetrated by one party on the other.

One problem is that the identity, because it is anonymous, it worth fundamentally less for this purpose than any real identity. The ransomer could decide law enforcement is getting too close, and stop responding to all payments, or abandon the system and someone else could take it over. For any identity used just for this scam, the loss of reputation is irrelevant, and if they are using the same identity for multiple scams they are inviting more law enforcement response. There are no future consequences of mention to screwing people over, since the identity can be changed at any time.
The only thing that really protects you in any of these situations are the incentives of the criminals, but those incentives, be they economic or liberty based, are subject to very different constraints than a legally operating entity. The bottom line is that the person or people involved has started the whole relationship by showing they are willing to screw you over. Establishing trust is not impossible (some people will trust), but it's very hard to do, a large percentage of will never actually trust you, and they likely shouldn't, because you don't have the same incentives or punishments they do.
