Someone posts that they are giving away a free $100 to whoever shows them they deserves it. One person posts (the post receives 1 point): Don't give it to me, other people deserve it more. The next person posts (the person also receives 1 point): If you give me the money I'll spend it to make the world a better place The final person posts a picture of a cat. His post gets -1 point. When somebody dislikes you comment you lose a point and when somebody likes it you gain a point. You can also vote on your own. Who gets the money?
The person with the cat picture. The other two people voted everyone's post down and voted their own up. But The guy with the cat picture voted everybody's post up.
