It looks like a lot of people want to self-host Lemmy. Would having an ActivityPub relay setup for those instances to subscribe to, instead of them all subscribing individually to the bigger instances be feasible? I’ve only seen discussions online about relays in regards to Mastodon. Has anyone attempted to set up one for use with Lemmy instances?
You’re not misunderstanding. They just solve more than one issue, and create a few too.
