For example here is a link for a blocked youtube video:
You are not allowed to view links.
Register or
LoginEverything what do you had to do is following:

You are not allowed to view links.
Register or
LoginNow you can watch or download this or other videos.
Pretty clever for a little duck. Don't you agree ?
