Be very, very careful about who you give information to!
Today, I got an "official-looking" e-mail from PayPal asking to confirm some information saying that "yadda, yadda" something was wrong with my account.
I foolishly followed the link within the e-mail to a website and got snookered almost completely. The site looked EXACTLY like PayPal's so I fell for it.
I called PayPal directly to confirm my suspicions and now I had to change all my passwords and get a new Credit Card!
PayPal straightened me out on their e-mail protocol and I gave them a copy of the e-mail that the impostors sent me. Hopefully, the perp that sent it out will get slammed by the cops.

So far so good -- no irregular charges to my OLD credit card (the number's gone baby and I get a new card next week) and a new lesson learned.
Believe me, I'm not a dummy that generally falls for this stuff but the Internet crooks are getting smarter all the time!
If a service EVER asks for confirmation of your information through an e-mail, go to the usual SECURED website (DON'T click on the links in the e-mail!) and call them through their help assistance line to verify if the e-mail is legit.
I'll bet you 99.9% of the time that the e-mail is a scam asking for personal information so that an identity thief can really screw you over.
Identity theft happened to every member of my family but we all took immediate measures to cover ourselves...
I've been hit by Internet crime twice, the other members of my family I suspect had numbers stolen by crooks at stores.
