I have an Australian namesake and one in the USA. They keep on registering for stuff using my email address. I was the first to get our name - [email protected] - but they seem utterly unable to understand that they don't have it - and they have [email protected] and something else.
I have tried asking nicely - but they seem to not get it.
Today I've had a confirmation from a website that I've been signed up for an account using my address - by my namesake's wife in Australia.
