I just thought about something interesting especially regarding Google AdSense. I am not sure if this is the case, but I have heard that you are not allowed to use traffic generated from Traffic Exchanges to a site with AdSense ads. I don´t know if this is true or not, but what if this is true? And what if I have a person that I don´t like that much and I really wanted to hurt him and his income.
Could I just generate thousands of hits to his site with AdSense ads and this would get him in trouble with Google AdSense? And to my knowledge, Google AdSense will just kick you out without asking you any questions. That is, if they believe that you are a cheater.
I hope the scenario above is not true and that it can´t be this easy to get someone in trouble. If so, keep your friends and be nice to everybody both online and offline 🙂
