A friend of mine in Canada receives a lot of email for a moron of the same name in England who thinks he has the same gmail address. This moron appears to be quite wealthy since the emails are often recepits for sports car repair, yacht club activities, swanky hotels and once very expensive houses. He has tried informing all of these companies that he is not their customer but none of them care and the person who is using his email address doesn't seem to care that he never gets his email receipts. The latest is an appointment at the Citizen's Advice Bureau later this week to get help filling out forms - perhaps he's fallen on hard times and needs to claim benefits now?
I wonder if reporting them all to the ICO would help.
