Yes, I talked about the client perspective but the relay part is also really important, of course. As you say, at relay side things are harder since they don't have direct access to the social graph.
The usual proposals here seem to point to PoW, a payment or an invitation, to unlock access. But I fear that all these approaches could create a lot of friction and slow down onboarding.
Even network filtering does not seem very effective, when you have disposable key pairs and VPNs.
I would avoid to delegate to AI this job, this would really escalate to an AI vs AI fight.
Do you have any other ideas?
