Yeah I just cloned Misskey and didn’t see the word anywhere in the codebase so I was scratching my head wondering if they had a Japanese word for the same idea.
Anyway, in light of the facts that I don’t see Pleroma absorbing Funkwhale Audio actions soon, ActivityPub is too open-ended for there to be a definitive “proper” use in the first place, Pleroma scrobbling has been around for a long time, and changing the way Pleroma ingests scrobbles would create a need for a migration to retroact all the previous scrobbles… I don’t think it’s worth it to do the change. Just leave it be.
Just my view on the subject.
