No, you don’t have to bother: the email addresses are rarely used for contacting people anyway. The main practical purpose of the email address is to determine the icon – the Gravatar – by the left hand side of the comments, which serves as an identifier to assure readers that any comments under that name are being posted by the same person. So please retain the email address you are already using.
Your suspended comment has now been approved, albeit shorn of the potentially offensive quip that was tacked on to the end of it. You’re welcome to include light-hearted banter, but discriminatory terms and tropes should be avoided where possible.
