Following up along this line, one thing I recommend most people consider:
Get an iTunes gift card, pay cash for it. Then open an iTunes account with this card and a new, single-purpose webmail account. It's a little tricky IIRC, but if you do it correctly (I know for a fact you could do this several months ago - I did it), you can open an account without a credit card or any other (verified) personal information. This allows you to legitimately purchase music and apps without divulging any personal info for them to use/misuse/abuse, give away or sell.
This also gives you the peace of mind knowing that even if another scammer in China figures out how to tap into iTunes accounts and steal from users' credit cards again, you'll be safe. All you'll ever have at risk is the $15 or $25 that you keep in that account.
Thanks for the advice.
A VAST majority of us have no problems at all with our iTunes accounts.
