Sometime in the future all I need to do is pay a hacker to get me a password for one of the admins. Then I can just start deleting comments all over the place and antp will have no way to keep up or where I started or ended. Even if the site saves everyday it will save with the things I have deleted and he will have no idea what I have deleted. If he restores the site from a previous time then he will lose everything that has happened since then.
