always wondered this, but kept forgetting to post it
eg users would be on @grant@toast.ooo and a community would be on @canvas@group.toast.ooo or something like that
then it would still follow the AP spec but still allow for identical identifiers (like a user account being @sc07@toast.ooo and a community also being !sc07@toast.ooo)
That would make community names a bit longer so they’d be more annoying to type and share?
if using lemmy, it could automatically make this change
this would primarily be used by other fedi platforms to easily differentiate community & users
eg if i followed
@sc07@group.toast.oooon mastodon it would for sure follow [email protected] and not @[email protected] (an account with the same identifier)
