I personally hate to get invites from my friends to install some facebook applications. I was not interest ever in getting such invites. There are huge amount of people who hate getting invites from friends to install facebook applications.
You can permanently block all those disturbing elements ‘facebook aplications’ which post message to you wall without any permission. Many of you even like such invites, specially newbie.
Here I will help in blocking all facebook applications :
To block the Facebook application platform, get login to your facebook account, then select privacy Setting under Account and then click “Edit your settings” under the Applications and websites section. There you see an option of turning off all the platform applications with a click you can block all Facebook Applications.
