I have been getting lots of more clicks on my dating site http://www.DateWealthyWomen.com , but my earnings have not really increased at all. It seems like Google wants to "CAP" your earnings. Has anyone seen similar results with their adsense accounts?

Google can detect repeating clicks. It does all kind of checks such as IP. It will not pay for not valid clicks. It would discourage advertisers of their Adwords program.

I don't think they would be trying to make few extra bucks and risk loosing their reputation.
