> In a simple test, the organization tracked down two existing Facebook pages – one pro-Israeli, and one pro-Palestinian – and uploaded content to each that was rife with incitement to violence and hate.

Sample size of two is just another anecdote.

Anyone who's reported large numbers of Facebook pages - like https://twitter.com/monteiro, who's been on a anti-gun sale campaign - knows getting a page taken down often depends on the random reviewer assigned to the case. I've personally reported the same page several times before someone at FB says "yep, deleted".
