So I got a very vague response from Google. (I'm sure they don't want to let too much information out, nor they want to get bound to new terms other than the ones states in their AdSense TOS). Google's response: But there are still few interesting points: - YOU are responsible for where your ad shows up. In other words if all of us have adsense accounts and constantly view each other's posts, and even sometimes click, it may be triggered as a red flag and considered a click ring group. - If that's the case, I could EASILY shut down all competitors by creating bogus sites that state: "Pleace click the advertisement below" with THEIR AdSense publisher ID and report them. Either way... I have removed myself from the profit sharing as it seems that it may be a risky area... And the $1/mo that it would generate is just not worth it.
