Good question. I don’t think so, because Loops is more like Mastodon (user centered) rather than Lemmy (interest centered).

Dansup posted the details here blog.joinloops.org/loops-joins-the-fediverse/

I never understood how Lemmy <-> Mastodon integration works. But I know that people who follow me on Mastodon got posts on Mastodon by “me” that mirrored my posts on Lemmy.
