Well, maybe privacy too lol, because I ran r/privatelife to counter the Reddit privacy cabal nonsense, and as soon as I announced a full migration to and primary platform being Lemmy, r/privacy became completely shit, and r/PrivacyGuides was abandoned by mods/admins for lemmy.one PG instance.
I also helped make c/datahoarder atleast an official alternative for r/datahoarder community.
