(adsbygoogle = window.adsbygoogle || []).push({}); Well lately the number of accounts being stolen has increased. It even happened to my friend a few days ago. £400 was stolen off his credit card to buy items off PSN. Don't even trust friends and family. They can give it to other people thinking that the account won't be stolen but it there's always a risk. Anyway I'm just saying dont give you're account to anyone.

the security question becomes useless if your email adress on your account is changed

Above all, call Sony, they can change it back for you, it's not that difficult =/
