A connection between SERPs and email flood is not clearly visible by most of us until it happens and David Peck was among the people who got to understand it. A Google query for the word Gmail offered as a top result authority link a redirect to a Gmail page that opened a new mail addressed to him. This meant that everybody who clicked that link to go and check their email got a blank email compose page that already had his Hotmail email address filled into the Email to field. Many people sent either blank emails or just sent an email with questions regarding what happened.
This glitch was confirmed by Google. The company admitted that "some email addresses on public webpages appear too prominently in search results" and announced that the problem was fixed. David Peck who got around 500 emails an hour was thus not the only victim.
