applications are automatically unblocked after 6 months from the time you blocked it.
you go on application settings and you can block and unblock applications
No. they will not
no way :D
To gain access to FaceBook you need to ask the person who blocked it to unblock it for you.
you can't.
If you would like to unblock someone from facebook, simply go to your account settings and click on a button that says "Blocking". Once clicked on, you can see a list of people or a person previously blocked and simply click unblock and you are done.
Well you can't.
Send an email to the Facebook Help Centre.

First you scroll right down to the bottom of the page and click on 'Privacy'. Scroll down again and click on 'Privacy Settings' Then near the bottom of the page there should be three things that say 'Applications and Websites', 'Block Lists' and 'Controlling How You Share'. Click on 'Edit your lists' which is under 'Block Lists' and underneath the first two boxes there should be a list of people that you have blocked and you click unblock. This also works if u want to block someone (but the long way) hope this helped!
