If some of Facebook's own moderation team cannot differentiate between spam accounts and legitimate ones then what hope is there for others?
Facebook would rather leave 999 false profiles up and not accidentally close 1 genuine profile that just happens to look spammy. From their perspective, ruining someone's Facebook experience by deleting their account is worse than letting everyone else have a slightly worse experience (after all, even those fake profiles are generating ad revenue).
In contrast, Youtube is flagging, demonetizing, and three-striking channels left and right, using much more trigger-happy moderation (and even auto-mods) to control videos. They have plenty of content creators, but need to keep both viewers and lawyers happy.
Be careful that you know where you stand on these platforms, especially on important things like Amazon AWS accounts.
