One thing I'll give Facebook credit for in the case of content moderation is, Facebook is not decentralized like the Fediverse compared to on Lemmy, Misskey or Mastodon and etc.

Facebook has a whole centralized platform to moderate with all users. Compared to the Fediverse this moderation can be tough and very expensive. Facebook would have to pay a lot of moderators.

There are some problems known to occur however

There are some things that can slip through but with all this ai training more companies are moving towards ai moderation over human moderation that should reduce moderation costs and their profitability.

Some content Facebook doesn't seem to tackle unless a government complains to them, particularly if they know its something they know generates them money.
