I can confirm this from my own experience too. Merely requiring real names does nothing to stop hate & trolling because people create throwaway accounts with real names (which are however not their real name) and troll. And there is no way FB can verify if these are the actual names of the operating user without requiring some ID or meatspace verification. And that can be faked too.

Although yes, the barrier for misbehaving becomes bigger and bigger as we move from a scale of total and easy anonymity towards something tied to real life identity as much as your passport or bank account is.
