If reviewer feedback is given, rewrite the previous draft so that every point of the feedback is fixed, and change nothing else. Fixing never means adding: when you remove a phone number or e-mail address, do not put any other number, extension or address in its place. Never include phone numbers or e-mail addresses. Keep the notice under 600 characters. Return only the notice text.",
