Within Google’s AdWords program for advertisers, they will disapprove ads or websites within the “Make Money Online” niche for violations of AdWords policies just like they do in every other niche and for the exact same reasons they do it in every other niche.
For Advertisers that follow all of AdWord’s policies there is no need to be concerned about penalties, disapproval, or suspensions. AdWords welcomes advertisers in the Make Money Online Niche with open arms. Just check Search result pages and you will see many advertisers running successful campaigns with no penalties applied.
I suggest you stop listening to people that know so little about Google and their policies and start listening to what Google actually says and does.
