> Mastodon doesn't really have a good concept of unifying profiles in that way. I think you're looking at the problem from the wrong angle. There's no need for multiple profiles if you can easily participate and be a part of both communities but at the same time not be a user of any of them. That's the benefit that Mastodon doesn't have, because their model of how federated communities should work predates ActivityPub's spec finalization. I think your use case would be satisfied if as a user you could "subscribe" to all activities generated on a server (or multiple), while your account would be on another one. ActivityPub makes this flow relatively simple, and one of the projects I'm working in the space has it as a design goal: small instances addressing themselves to communities with relatively low numbers (500-1k people), but at the same time the participation and receiving of updates from any other community in the network would be a click away.
