I’m not sure if the protocol supports downvotes. I think nested comments could work with creative UI uses of username mentions. I’m sure this has been covered, links are appreciated

The short answer is, yes. The long answer is that Lemmy already uses activitypub, but is limited to other Lemmy instances until federation is more fleshed out.
The protocol doesn’t support emojis either, yet Pleroma and Misskey which both implement them can talk with Mastodon seamlessly.
Mastodon also has custom emojis. Though, Pleroma does have message reacts that only work within pleroma.
By emojis I mean the reacts
The ActivityPub specification allows for partial implementation: for example federating user profiles and comments for posts from Lemmy, while saying nothing about emojis, or upvotes. For example, Misskey also had polls way before Mastodon did, so it didn’t federate polls until fairly recently.
You can find some info about our activitypub implementation in the docs. The protocol details are somewhat outdated though.
Will lemmy use the Group model? It would be great to be able to follow a group from other implementations!
Edit: the model and everything in the docs looks sound, I guess the question is when will users outside of lemmy be able to follow groups, post to the and comment on posts?
