delete posts on Facebook profile page

deletePosts.js

/* After deactivating some Apps (eg Twitter, Yahoo Flickr etc), I noticed that I could not remove posts via GraphAPI
 * because it would be a defferent app from the app originaly posted statuses.
 * There might be a better to do it via offical APIs, but I was lazy and inspected some html class names to click
 * around on my profile page and delete posts.
 *
 * Usage:
 * 1. Go to your profile page and open Web Inspector Console (I used Google Chrome)
 * 2. Copy and paste the script below to the console 
 * 3. Ovserve how it's deleting your posts or just open another tag to go somewhere else
 *
 * NOTE: Those html tag class names are based on Facebook web design Nov 22nd, 2015. You might need to modify those.
