I’m still figuring out how it works, but seems Mastodon doesn’t sync the history too well, and only stays in sync if at least one person on the instance is following the community. Maybe the old ones are delayed sync, or someone that was subscribed then unsubbed before another took over? It’s getting the Snoo hug of death at the moment, so I’m expecting weird behaviour!
Not an easy problem to solve by any stretch, which is why I assume core functionality is the focus before doing it, but better than the multiple persona issue we have at the moment.
In my early exploration I have 1 Lemmy and 1 Mastodon account, but all my eggs are in one basket should it go offline. If I wanted to have choice of even 2 instances for each service, I’m now looking at 4 ‘handles’.
Not a fun problem to solve, but long term it’s not a great problem to have. At least if I can run my own identity server I don’t need to trust a single entity outside of me with my online identity.
