How is this going to help when admins aren't looking into hacked accounts? Many people have signed messages from addresses that are still visible, but they're just not being restored and theymos' auto-system likely isn't going to help that either as I doubt it will take into consideration deleted posts, but even if it does what if somebody has another or an older address posted. Can they still claim the account back?

If he has no time or desire, he may perhaps delegate this "power" to global moderators.
I say maybe, because I do not know how this power works on the forum and I do not know if you can pass this skill or he needs to create a new rank with more powers than a global moderator.
