Intriguing.
What's the mechanism for dealing with spammers?
In lemmy there's a clear escalation path that will lead to either the spammer's instance dealing with the issue or the instance itself being de-federated.
How would that work in a p2p system?
Each user having to individually block every spammer will work as well as it did for email back in the day.
Did you ask an AI to do the list for you? (no need to answer)
