When I logged into my AdSense account today I had a recommendation to turn on the ads that may show gambling and betting, so I did that. My site is about tourism and it is not targeted to gambling. Also, gambling is illegal in my state and the destination it promotes. So I am wondering if it is a good idea to follow Google's recommendation. Does Google approved sites before they suggest such ads? Also, do I need to include any disclaimer on my site that my site does not target people under 18?
