Facebook notoriously doesn't employ native speakers for all the languages the interface supports, so posts in languages they don't staff for have zero oversight.
In my sibling comment, I do point out some sources for English language nastiness as well.
They may not explicitly embrace it, but one could argue their erratic enforcement of the vague "community standards" is itself insufficient, if not simple lip service.
Also, back to topic: does FB show (e.g.) Disney ads on posts in languages it doesn't have moderators for?
