I have 35 sites with adsence on them, if I wanted to risk my adsence account, I could theoretically plop the ads into my gambling sites. I’ve always been a bit to fond of my adsene account to take the plunge, but it’s an option. For some it works well for a long long time. Others get banned right away.
A friend of mine has a blog with no banners, and actually emailed google and asked permission, the answer was no ty. As the blog doesn’t have any gambling banners, it does link out to sites with gambling banners.
But anyway the answer was no. Either way you’ll get away with it till they decide to put a stop to it, you might get paid for your efforts, you might not.
