Grapes is right. While there is a responsibility to not post private emails, there's no expectation of privacy in a public post, no matter how quickly that post is withdrawn. There is no difference between quoting from the email notification of the public post than there is to quoting the public post prior to the post having been "revised" out.

Rule 14 aside, if rule 5 applies to email notifications of public posts, then for consistency's sake, rule 11 really should be considered in play as well when those posts are revoked.
