Viral Script for Bebo, Tagged, Hi5, Facebook, Myspace etc...

I would like a viral script coded for a specific social networking site that works much the same as all the viral FB scripts have done. The main purpose of the script is to gain traffic by getting my website viral using one of the following ways: When a visitor from Bebo, Tagged, Hi5, FB etc... visits my website the following happens: - Auto posting on users walls - Auto post to friends - Auto status update with link - Auto comment - Auto comment on friends picture / profile The above are just examples of ways the 'Viral' part can be achieved. I am open to variations, I just want it to some how go viral! Just to make it clear I want the script for ONE social networking site! It is your choice which site.
