Probably better to post in the github issue rather than replying here.

hmm, how would the receiving instance verify? what happens if I send 100 random hashes?

This is literally already a problem. I can easily set up an instance and write a simple bot which just spams votes with randomized user strings. There are generally a bunch of these functional vulnerabilities in the AP trust model which are only mitigated by the current lack of scale. Work needs to be put into reworking the trust model, not exposing user telemetry to even more people.

Well you can do that for a little bit, until your instance gets found out and it gets defederated. And you need to pay for a new domain if you want to do it again. So the current system actually makes it cost real money to do this spam you're talking about.

Sure, but the detection and enforcement mechanism would be the same as it is now.

well, since the voting is public it's easy to remove your votes and block your instance after the fact

Each instance could store a static private key used to encrypt all usernames in that instance maybe?
