AdSense and Gambling Sites. Not Allowed

I ran into a bit of a speed bump earlier this week. I have recently created a few gambling sites, of which I mentioned here on this blog;

A Roulette Strategy Video Site
A Blackjack Strategy Video Site
A Poker Style Blog Video Site

All sites looked pretty cool and quickly climbed up the Google rankings and had decent SERPs. After throwing some AdSense onto the sites, I was seeing some good payouts based on the crowded gambling 'AdWords' bidding.

However, I loaded up the pages earlier this week and saw all the advertising from AdSense had stopped loading. I saw a considerable drop in AdSense revenue which explained the drop out. I received no email from Google, but after reading a few website and checking the TOS again - it seems AdSense isn't allowed 'with direct gambling (poker, blackjack etc) sites'. Now if you mention gambling terms as I am doing here in this post - it seems like you're ok. But flat out advertising on a gambling related site aint allowed.

A shame, but I have had to turn my video site focus to other areas - some of which are high paying keywords, but I will just need to boost the search engine rankings again for these newer pages.
