A friend of mine had an Adsense account and would click on his own advertisements while in school. He would do this every day in the same class. He would also ask other students in the class to do the same thing. Each month, he would show me the check he received from Google.
I too had an Adsense account but I ended up losing my account about a month later. Only problem is, I was running a legitimate forum in which there were 300+ people that were active. This forum was created because we all played the same online game and created clans. We used the forum to keep in touch with other clans and to strategize. Never did I click on my own advertisements.
Once I lost my Adsense account, I reported my friends account but nothing ever happened except he kept receiving his check each month.
If that's all there is to the story, you come across as a bit of a dick. If you didn't have any problem with his behaviour when you were getting paid, why did you report him when you were banned? I'm not saying reporting him, out of context, was the wrong thing to do, but the context you provided makes you seem petty.
