Post (BUYING) Facebook Viral App (Autoshare, Autopost friends walls, autolike)

Hello..
Im looking for an application on this,
Its for a contest, I need to add a button on my landing page that says, CLICK HERE FOR SUBSCRIBE IN THE CONTEST.. the popup the confirmation to connect with facebook.
After clicking the confirm button, then on the backend, Automatically post a message with a youtube video on their walls, and automatically post on some friends walls about it too.
Is this possible? posting to other friends walls?
And the final step, auto liking a facebook fanpage.

Please answer here your opinions on how we can improve this and PM with a price.

It was possible some years back. Facebook is getting strict day by day and I haven't seen any such viral application running these days.

wow are we back in 2011??
