That sounds terrible. The whole point of a social network is to know what somebody is saying / has said. It isn't about democratising the spread of factual info

That sounds terrible. The whole point of a social network is to know what somebody is saying / has said. It isn't about democratising the spread of factual information. If I say x, but somebody else thinks I should have said y, who cares? The point of a social network is to let people know that I said x. If x is wrong, the point of a public encyclopedia (like Wikipedia) is for people to be able to read y. But for a social network, this does not seem like a useful feature at all.
