It seems that lemmy.ml is a FOSS and privacy focused lemmy server run by two of the delevelopers of lemmy. Descripton of lemmy.ml is “A community of privacy and FOSS enthusiasts, run by Lemmy’s developers”. Due to that, it seems to be more limited: NFSW blocking, account (like in the mastodon instace of fosstodon.org) and community creation is reviewed to avoid creation of accounts/communities not related to the server.
And lemmy.world would be a more widespread server with the advantage that account and community creation is not reviewed. One new fediverse user that want to post to the PTA community would probably select the same server of the PTA community for its account and it would create the account without review.
