OPEN BLOCKED VIDEOS ON YOUTUBE WITHOUT HAVING AN ACCOUNT

In this tutorial, I'll show you how to watch blocked YouTube videos having an account.

Method :

First, we need a link to a 18+ video.

For example, I'll be using this one:
http://www.youtube.com/watch?v=LqWIvFeEhiI

Now do this:

http://www.youtube.com/v/LqWIvFeEhiI?fs=1

And you will be able to watch it.
