With all due respect, you're not thinking like an activist. Facebook certainly discourages this kind of behavior: they don't allow pseudonymous accounts, and there have been repeated problems with them shutting down human rights pages and groups. But it's the easiest way to reach people. So activism strategies adapt accordingly.

Back in 2009, for example, the key Mousavi Facebook page is run by somebody outside of Iran. Supporters who want to expose themselves publically can 'friend' the page and easily share information publically; but people who don't want to can view it without being on a list. Similar things are happening in Tunisia.
