Not a full solution, but... can you block users by wildcard? IMHO everyone who has ".eth" or ".btc" as their user name is not worth listening to. Being a crypto bro doesn't mean you need to change your user name... unless you intend to scam people.

I'll revise my opinion if rappers ever make crypto names cool.

Long before cryptocurrencies existed, proof-of-work was already being used to hinder bots. For every post, vote, etc., a cryptographic task has to be solved by the device used for it. Imperceptibly fast for the normal user, but for a bot trying to perform hundreds or thousands of actions in a row, a really annoying speed bump.

See e.g. https://wikipedia.org/wiki/Hashcash

This combined with more classic blockades such as CAPTCHAs (especially image recognition, which is still expensive in mass despite the advances in AI) should at least represent a first major obstacle.

To help fight bot disinformation, I think there needs to be an international treaty that requires all AI models/bots to disclose themselves as AI when prompted using a set keyphrase in every language, and that API access to the model be contingent on paying regain tests of the phrase (to keep bad actors from simply filtering out that phrase in their requests to the API).

It wouldn't stop the nation-state level bad actors, but it would help prevent people without access to their own private LLMs from being able to use them as effectively for disinformation.
