Tor means they can sneak through state-level internet blocks and surveillance. Once they&#x27;re on Facebook, they&#x27;re (ostensibly) obeying their Real Name policy, so Facebook knows who they are. Their Tor support doesn&#x27;t protect their identity or communications from Facebook itself, other than obscuring their IP address.<p>Encrypted chats, on the other hand, treats Facebook itself as untrusted. It lets people use Facebook without Facebook knowing exactly what they&#x27;re up to.
