@nyquildotorgJer #Mastodon and #ActivityPub needs a mechanism where domain names can be recycled. The fact that WordPress alone has no mechanism to allow a domain to exit the fediverse is reason enough. Sometimes servers get bricked and there is no way to go back and self-destruct.
Domains could be validated with a text record in the DNS by the owner of the domain name. If text record ActivityPubKill is true, then it should be trusted as so and defederated.
I'm not sure how this could be done, I don't know the ins and out. Maybe software packages could poll the DNS of failing federated servers and look for a universal or software specific kill tag or a file could be placed somewhere on a server that it looks for when a server fails, esp after 7 days.
Either way, a dns entry or a file on a physical server can be a trusted source as it takes elevated permission by someone in charge of a domain to usually do such a thing. #MastoDev #MastoAdmin
