anyone performing actions that hurt others where its not really about themselves. being mean for no particular reason or reward, especially to themselves.
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.
the party of projection at it again. you can be sure if theyre claiming others are doing it, they are themselves guilty of it. waste? fraud? dictator-like behavior? all things that orange piece of shit is actually pursuing... but only if you judge him by his actions and words.
grab a personal domain, setup smtp through proton then have your local mail client archive via imap
email is the only service i would never self-host directly.
