People put up all those unflattering things about themselves online without being forced to. Those are true, even if not full, representations of them. But that one-sided representation is exactly how the person wanted to be seen. They always have an option of showcasing a better image of themselves (through photos, videos, blogs, etc.) online, but nobody owes them the right to undo something they themselves freely shared. It might be a mistake they realise later on, but mistakes do not create a right to erase everything about that mistake. Nothing in real worlds works like that – you might have made a mistake by getting to drunk at a company Christmas party, but you can't insist on co-workers pretending that never happened and not telling anyone.  Moreover, there is plenty of information about how to act on the internet [5]. So we should not grant such a right to someone who did not learn how to act on the internet - they'll have to learn the hard way.
