Sort of related: I learned from reading about Facebook's lack of moderation that Myanmar is one of the few countries that doesn't use Unicode (and hence UTF-8). It uses something called Zawgyi that apparently has to be heuristically detected!
Facebook is despicable and indefensible. They knew that they could not moderate Myanmar. They knew or should have known that it was a volatile political situation. The amount of money involved could not have been more than a few million dollars. They should have just turned everything off and said we'll come back when we can. It's disgusting what they did and they should never be forgiven for putting market position ahead of human lives.
