With Mastodon you can migrate your account, Lemmy can’t migrate (yet). But the difference between Fediverse and commercial platforms is that you can access the same network of content from different instances. With Twitter/Reddit etc. everyone is forced onto a single instance (and a single moderation policy).
How?
Can I just move my existing account to a different instance? Or do I need to create a new account on another instance?
