Below is an email I received today. Yep, spam, we can all see that. But look who it's to.
I own the email address @taximania.co.uk I can use any word before the @ symbol I want

When I signed up for a Tesco credit card I used that email so it was memorable and unique.
Tesco have sold or passed on my email address and somehow the spammers have got hold of it.
Just shows that even the big retailers and banks etc share your details

I have since changed my email addy for my card

not stupid
