I feel conflicted about upvoting. The "Facebook knew and failed to act" framing is ridiculous. So is complaining about casual access being closed off for a document that is clearly highly likely to leak. (And honestly it looks like something that should have been need to know from the start.) But the leaked document itself is fascinating, both as a post mortem of sorts and as an example of high quality anti abuse work. It is an area where little gets published for obvious reasons, and every group needs to learn the same lessons from scratch. Great read.
