Here's a new one!
I have three email accounts, but only ever use one for outgoing stuff - the others are used for blogging etc.
I very rarely look at the latter two, but just last night, by coincidence, (fiddling around with an iPad), I saw an odd email from the US Social Security Administration, telling me that my social number and email address on one of the 'spare' accounts was being used for illegal actions, and I was being suspended!
Funny that - the last time I looked, I don't have a US 'social number', I live in Kent, England, I actually exist on our British pensions with Mrs Growster, and as far as I can recall, have never spent any money in the US except on holiday - paid for in English Pounds nearly thirty years ago!
I wish they'd keep up...;0)
