Interesting history and analysis of SMTP’s history. How can we prevent fedi and other open protocols from suffering the same fates?
Why don’t they use existing domains? I don’t think 100% of them require a phone number. And didn’t know it’s possible to defederate an email provider.
No, my point is that if spammers were to spam on the fediverse, they’d need to buy new domains constantly as their previous domains are defederated, I’m not talking about email.
So you’re offering a system that requires the instance/provider admins to manually federate with others instead of the federation being enabled by default?
You’re misunderstanding me again. Please try reading what I said again.
I’m not suggesting allowlist federation, though that is another tactic that could be used. I’m just saying that a spammer on the fediverse would be quickly defederated and would have to buy a new domain to keep spamming, which would probably be too expensive to justify.
