Once upon a time I played a game with a friend, it was warhammer or alike, I can't remember. We were in the same house, two different room, same net. We just played it for the fun of it. So I thought. He always won. A day I discovered why: he was cheating.
It was just a game, no money, and yet he liked so much the idea of being the winner, that he decided to cheat. I couldn't understand: where's the fun? I believe the fun it's to win complying to the common rules.
Now think about it when there are money involved. People get stupid. They act strategically to gain money, beyond any other meaning in replying, resteeming, upvoting and so on. It's human being at his/her “best” (sarcasm).
