G doesn't encourage it, but i don't think you'll be banned. unless you're talking about placing your ads in the poopunders.
Advertising to drive traffic to your site is not disallowed. I use AdWords and I do some print advertising to help find customers. However, I would not use pop unders and such because too many people use software which blocks those types of ads.
As long as your site is the recipient, I believe that you will be fine. You can e-mail to be certain, but be careful to explain what you want to do in detail and without using any slang.
