"Critical concept: IRIs are opaque identifiers. You cannot infer meaning from the string pattern — only by dereferencing and inspecting the data." [1] This applies to URIs too. Sadly, almost no #ActivityPub implementations use this principle. Multi-tenant servers and simple account portability (with personal domains) would be relatively easy if they did.🙄 It is what it is...
