My understanding of federation is that it’s like email. If one server is misbehaving, then they get defederated.
So how come email spam still exists - why don’t spammer domains get defederated? It seems like we’ve got the worst of both worlds, where it’s hard to get your emails relayed when you run a small email server, and easy to get them relayed if you’re a spammer.
Is there anything about Lemmy’s architecture that will prevent this problem?
they do get ‘defederated’… by way of automated block lists by domain and IP…but the issue is smtp due to age is trivially easy to setup on new domains/ips as well as dns and relay tricks to obfuscate the true source.
