I think it was clear that you want to destroy Facebook.

What is not clear is how 0.1% of users publishing their Facebook passwords on Twitter or Reddit would bring about the destruction of Facebook. It looks like[1] Facebook grows by a little over 1% every quarter, so I don't understand why Facebook would collapse if a tiny fraction of their userbase started posting spam. In fact I imagine their existing spam-fighting tools would not have much difficulty handling this kind of thing.

Facebook itself estimates that 5% of its monthly active userbase is made up of spam accounts.

You can't use Facebook to destroy Facebook.

Their terms of service are not immutable laws. If the status quo stops working for them, they can restore old data and alter the bargain further.
