But I'd just relax if I were you, nothing you can do either way. I trust you've deleted your AM profile though!
Ah, there's the rub! The theiving bastards at AM let you sign up for free, and any further activities require a credit card, which even extends to deleting your account. So, if like me, you signed up to see what it was all about and whether it could be cheaper than punting (yes, idiotic I know) and decided you didn't want to give them your card details you couldn't actually delete your account without entrusting them with more details than I was prepared to give. Fortunately my account only has a hotmail address with a fictitious name, so the hackers are welcome to it!
