Somebody sent me this. It's from last year. It appears that Facebook sub-contracts its moderation, at least at the "first level". A former Moroccan employee revealed the rules for censorship.
I see that this is a culture-based censorship check list. Depicting camel toes and moose knuckles is...not..allowed. Ear wax either. But crushed heads is fine as long as there are no internal organs showing.
I can't vouch for it for sure... I'm not going to try to post ear wax or moose knuckles to see if it really does get censored. Just thought I'd put it out there, for anyone to browse.
