I have a first initial last name email from the early days of gmail. The amount of PII and private conversations I've received is incredible. Someone on the other side of the country tried to email himself his business loan application... twice.

Hah that happened to me a few years ago too. HSBC emailed me all the login details for someone’s internet banking account. I emailed back saying they had the wrong email address for their customer. They said if I wanted to change the email address on the account I’d need to go into a branch to do it. It took several attempts back and forth before they finally just disabled internet banking again for that account.

But that was way too much effort. I don’t bother now. My Gmail address (josephg) is a cornucopia of junk. It gets the pay slips from a mechanic, lollypop orders, delivery notifications for shoes, Indian cell phone bills, and all sorts of things. I declared bankruptcy on that account years ago and moved on.
