Also: most Facebook users probably don't know that after you delete a photo, it's still available to anyone on Facebook for up to 30 months. All they need is the URL of the photo, which never changes.
The biggest threat to privacy and security and Facebook remains the oldest: falsifying accounts. Anyone can set up a Facebook account using a false name. That name can be somebody else's real name, or they could just make one up. Strangers can pretend to be your real friends on Facebook.
Once that friendship connection is made, they have access to all the information they need for first-rate identity theft. It's also great for real theft because if you post that you're going on vacation, they can burglarize your house.
If you think the solution is to simply not have a Facebook account, think again. Anyone who signs up for a new account on Facebook can demonstrate this. When you first sign up, Facebook presents a list of people who are probably your friends this happens before you even invite others to become friends on Facebook. And the list is usually pretty accurate.
Stated another way, by not having a Facebook account, you leave yourself open for this particular scam. I hear my fellow tech pundits and columnists brag in writing online that they don't have Facebook accounts. Once a crook knows this, he can establish an account in your name. Facebook will provide him with a list of many of your real friends.
He can establish those Facebook friendships, then reap a harvest of personal data about you that enables all kinds of mischief.
The bottom line of all of this disturbing security news is that if anyone wants to steal your information, pretend to be you, burglarize your house, stalk you, well if youre account is not properly protected Facebook is one-stop shopping for all of that.
Facebook's security measures fail to impress. They don't solve the real problems and, in some cases, even create new risks.
Users don't care enough about security. And Facebook doesn't care enough about security.
It's time for Facebook -- and Facebook users -- to finally get serious.
