This is specifically about Facebook selling Ads. Don't broaden this to be about policing all speech on their platform. If Facebook sells ad space, they 100% are responsible to vet that the ad meets their standards before publishing. Not being able to read it because it's in a language Facebook is incapable of reading means they either need to decline to publish it (and not take any money) or hire appropriate staff to vet it (and pay them using the money you get from selling the ad).
