Click Jacking

How do people make it so if you click a URL it makes them auto post the link and like their facebook page? This went viral and infected over 80, 000 people in a week and I want to make one to get facebook likes and to make it go viral?

Did you search the forum?

People have shared scripts in the past, if you don't find any then try the WTB section.
