How to use facebook-authorization, and not allow any site to litter on your behalf

Facebook-authorization - a great way to start using the new service in 2-3 clicks. There is no need to enter usernames, passwords, shipping avatars and so on... But there is a problem - the application or web service acquires the right to post on your behalf the devil knows what in your profile, thus causing tics in your friends. If you do not put to rest, it will be filtered once all your friends, and your posts, links and seals pictures stop-achieve goals.

This is how to stop the willful behavior of the sites on which you used the facebook-authorization.

As soon as you press the button like Signup with Facebook, you will see here is the standard popup-window. Choice then you do not have a lot of - click Log In with Facebook. But almost no one notices setting permissions for a Web application:

I'm using facebook-authentication, enables service to make publishing Only for me. None of my friends will not be disturbed by the new service, which I'm testing for Layfhakera. And if the service grows in insolence on my wall (see just me), then I had to cut.

At this disregard this setting, users built most viral mechanic, especially in branded sites and applications. So do not be a part of a mechanic, be thoughtful user.
