We've all heard the "rigged" debate. But when people say online poker is "rigged" in what way do they mean? Like, they have a personal agenda versus certain players and make sure they lose? WTF do people mean exactly? And, what would be the purpose of a site "cheating" player vs. player when neither represent or work for the site?

Please explain in what ways you or others think the site is rigged. And, what you think the site has to gain by cheating players.
