Scams and fraud involving Gmail addresses
If your credit card was used without your authorization, we recommend contacting your local authorities, your credit card company, and any website where the credit card was used.
If you have observed or been the victim of illicit activity on a non-Google website (i.e. Craigslist, Ebay, Paypal, and other sites), you'll need to contact your local authorities and the specific website that was involved.
In either case, you may also wish to file a report with the Internet Crime Complaint Center (www.ic3.gov), a partnership between the Federal Bureau of Investigation and the National White Collar Crime Center. Unfortunately, Gmail is unable to participate in mediations involving third parties, or track suspicious credit card activity.
If you wish to inquire about a Gmail user's involvement in a scam or identity theft case, please note that in accordance with state and federal law, it is Google's policy only to provide this information pursuant to a valid third party subpoena or other appropriate legal process.
