The moderator view of user profiles includes an "email" field with the default text "
(click to show)":
In times past, clicking it caused it to reveal the user's email address, but this behavior seems to have changed* to taking me directly to the "contact user" page.
If this is intended, the text should be changed. Perhaps it should read "
(click to contact user)".
* A reasonable change, in my opinion, as there's no reason for a moderator to use this information to contact a user outside of the Stack Exchange framework.
