The firm has had to really bulk out its policies over the years, what with hate speech, fake news and so much more.
Falling foul of the rules could lead to a temporary suspension – or worse, a permanent ban.
But some are more obvious than others…
Not using the correct name
Facebook doesn’t want any old thing used as your name.
Facebook shutting down one of its BIGGEST features in shock u-turn
As the rules state: “The name on your profile should be the name that your friends call you in everyday life.
“This name should also appear on a form of ID or document from our ID list.”
This means symbols, numbers, unusual capitalisation, repeating characters or punctuation are not allowed.
That said, unless it’s offensive, Facebook are unlikely to notice.
Not using your account enough
If you don’t log into your account for a long time, Facebook may decide to delete it altogether.
It’s not clear how long you have, but Facebook’s policy site says it could “empty accounts with prolonged dormancy”.
The firm will “seek further information about an account before taking actions ranging from temporarily restricting accounts to permanently disabling them”, so you may well get an email warning you before.
Nudity and sexually suggestive posts
Facebook does not want nudes on its platform.
But the rules have had to be refined over the years, to distinct the sexual from the non-sexual.
So visible genitalia is not allowed except in the context of birth giving and after-birth moments or if there is medical or health context situations.
Female nipples are banned too, unless it’s showing breastfeeding, or for medical and health reasons.
But detection tech has not always worked properly and some accounts have been incorrectly banned.
