Why don't you think they have one? Let's take a second and think about how awful Facebook would be right now if they didn't have the protections they have in place already.
Taking an isolated incident of community reporting taking down some posts and accounts doesn't show in any way that they don't have protections against bot rings. What if it's legitimate users who have a vendetta against the protesters? Obviously, that doesn't make the end result OK, but that wouldn't be some weird evidence of technical neglect by Facebook.
That sure was the case in Ukraine during the was and it's going on on now with Saakashvili. Lots of people just tag everything as porno and user who posted this goes to ban.
When you are trying to appeal, it obviously goes to somebody who should know the language post was written and it happens to be some Russian, who also flags it.
I doubt that this is an isolated incident. I've directly seen a few cases when content that was unpopular with a large group was removed for ridiculously false reasons and heard of various FB groups trolling each other by getting each other banned.
