I think we can all appreciate that Facebook is focused on creating a safe, spam-free environment made up of real people. That's why so many of us are there, right?
But it doesn't make sense for us to go on investing ourselves into a system that will 1.) abruptly terminate our accounts for the merest suspicion of unacceptable activities, 2.) provide scant evidence of our misdeeds, and 3.) give us such vague remedies for resolving in a timely and predictable manner. This kind of system asks us to abandon our online social experience to a closed and authoritarian police state, albeit one that lets me "poke" my friends ;)
I'd hate for Facebook to think that its success is *due* to its closed, top-down processes (rather than despite of them). Either way, I'm sure that the Facebook community can suggest some alternative approaches that will promote FB's core values while still embracing the transparency and humanism that sustains the most vibrant online communities.
