Hi,
I always thought Casino / Gambling related content was a big no-no for AdSense. I got that weird idea by reading their policy on content, also known as AdSense TOS..

Well it seems I was wrong.. On an official (adsense help) I've found out that in fact MANY things related to Casino / Gambling are allowed and only a couple are not. Like having an actual gambling site and putting adsense on it, or linking to such a site directly, without being a referral..

Did you know about that or wasn't I the last one to know about it?
