I would add that, broadly speaking, any online system that tries to engage and involve everybody will always become toxic. Forums like those of HN work, in part, because they're not trying to attract everybody, only those who will contribute thoughtfully and meaningfully.

Isn't Facebook dependent on backbone service providers at their data centers? Are those vendors at liberty to discontinue service?

Edit: For a multitude of reasons - money, money, and money - I don't expect any vendors would discontinue service with Facebook. The question is more of a thought exercise.
