How to OPT-OUT from Facebook's Facial Recognition feature that may put your privacy at risk

I have previously posted the Facebook's new facial recognition privacy problem, a lot of my friends are asking me how to OPT-OUT of this service with their own privacy concerts.  I then dig around and finally found good options for it.

I have personally tried the method 1, and method 2 seems hard to verify if its from auto tag or your friend tag you manually.  Beside method 1, rest of those methods are preventive and are only trying to confusion their system.  They are not guaranteeing to work.  I will only recommend you to use method 1.

1. Disable the Facebook facial recognition auto-suggest function for photo tagging.
Go to Account (upper right corner of homepage) - Privacy Settings - Custom settings (bottom middle) - Suggest photos of me to friends - Enabled/Disabled (check Disabled)

Things others Share -> Suggest Phones of me to friends

2. Vigilantly monitor your notifications about being tagged in photos so you can be in control of this data.

3. Upload pictures of celebrities or other people and tag them as yourself. The point is to pollute Facebook’s facial recognition database of you so that its ability to identify you is weakened.

4. Request Facebook to remove your "summary information" from its facial recognition database (hat tip to PCWorld).
Login to Facebook - Click on this link - Click the "contact us" hyperlink (In the sentence "You can contact us to request that we remove all of your photo summary information") - send Facebook the automated message that pops up in the box
