In some ways I feel that those people have consumers remorse. What I mean is, they started sharing and then realized "Hey, the whole world can see my masterpiece of feelings and now I feel emotionally threatened/embarrased." Because they feel its a masterpiece (pure speculation on my part) they refuse to delete it and when its too late they feel bad. It's up in the air whether I think we should give them a free pass on their goof up (that they make over and over again!)
