This is pretty much old news, going back to the leaked document that gawker got in 2012 (http://gawker.com/5885714/inside-facebooks-outsourced-anti-porn-and-gore-brigade-where-camel-toes-are-more-offensive-than-crushed-heads).
What I can't tell for sure, and as someone not particularly affiliated with the Kurdish or Turkish causes, haven't experienced directly, is Facebook applying all of these standards (e.g. denigration of Ataturk) to all Facebook users, or does it only affect users from Turkey?
That is, if I post something denigrating Ataturk, will they potentially block it entirely or just block it in Turkey? If it's the latter, well, that's unfortunate, but that's Turkey's anti-free speech laws. If it's the former, that's especially repulsive, and basically pushes Facebook to the least-common denominator of free speech.
At any rate, the Turkish government's sensitivity to "insults" against Ataturk are somewhat ironic, since Erdogan is doing everything he can to spit on Ataturk's policy of strict secularism.
