Hide your Email Address from Facebook Apps
As any Facebook user, you must have played around with the millions of apps available to you. But playing around with them requires you to add them access to some of the data in your Profile like your email address. I am sure all the Users of Farmville or CityVille(Developer Zynga) are familiar with this
Here is a sweet method to avoid such apps from getting access to your Real Email address.
Whenever you are trying to add an app and it asks for your Email Address, just click Change under “Send me email” and Facebook will offer you a new and anonymous email address that you can share with the app developer. (See above Pic)
Any messages sent to this address will still go to your main inbox but via the Proxy address (while your actual email address will stay hidden from the app developer). Also, once you remove the app from your Facebook profile, that proxy email address will be rendered useless too. Sweet, Huh ???
