It totally would. In ActivityPub, all objects (like users and posts) have an identifier that includes the domain name. For instance, your ID is
https://midwest.social/u/m_f
. That's what identifies your user. There is no way to change an ID - the point of an ID is after all that it stays the same and still refers to the same entity. This is a pretty serious limitation of ActivityPub right now unfortunately.I wonder who was the idiot who made a persistent ID for identity reliant on a third party factor that can be trivially taken away.
Any plans for solving it that are known?
Not as far as I am aware - I don't think you can really fix it within the protocol, i.e. without a breaking change. Then you may as well make a new protocol.
I think there's a FEP that could (or fixes) this. To my understanding ID can be any URI, so there are better ways. I guess it's hard because it would brake a lot of stuff or how mastodon is build.
Any FEP trying to fix this will be incompatible with existing instances, so I don't really see how it's gonna work.
Yeah, it sucks. But I think that at a certain point it will need to happen if we want to make ActivityPub better with better portability.
