The policies for placing ads to sites where you promote offers about making money online are very harsh now on Adwords and Facebook. If you set up a Google Adwords ad that links to a make money online site where there is NO PROOF people can actually make money with the system, you get a warning and if you don't change the content of the site you get banned. It happened to me and I had no idea of this very strict policy. Google is not at it's best about warnings and explaining what is wrong with your ad, they simply send you links to standard rules pages. On facebook for the time being the ads are simply refused, without further penalties. Just to let you know and as said be very careful!
