Assume for the sake of argument that facebook users make one-million posts a day. Assume it's spam detector is 99.999% accurate at telling if a given post is spam or not.<p>That's 10 false positives _every single day_. And in all likelihood their spam detector isn't that good, and there are many, many more posts than that.<p>Every now and then one of those false positives will be an interesting web site or one that feels really obviously wrong. But that's just what statistics does. When you take enough samples from a distribution, even very low-probability events happen.<p>Sometimes something will feel really out of the ordinary and wrong, but it happened entirely by chance.<p>If there were evidence of systematic decisions like this, it would be more of a story. But what we have here is just a big nothing-burger.
