Is it possible? I’m with sh.itjust.works but I saw a few posts who were saying that my instance blocks certain stuff. Now I’m not thinking of jumping ship right this second just wondering if that is a possibility.
For a little perspective:
Mastodon has an official way of migrating your account. It migrates your followers and accounts you follow, but doesn’t migrate your posts afaik.
Migrating posts (and comments in Lemmy’s case) would be iffy in itself imho and I’m also not sure whether that would even be possible since posts are synchronized to federated instances, where they would have to be updated too.
