Ehm, okay, that sort of makes sense. It makes the other places that still show emails make even less sense though 
Right, so with that on (it was off by default), moderators do get the same set of “show” buttons on the profile. But perhaps that setting should then affect the user list page as well (if we don’t want moderators to be able to see emails, the button shouldn’t be there either right?) and indeed the email log page…
