A while back, there was someone on ebay selling "interstitial" traffic. That is just traffic that involves a page that is not a pop-up but a transitional ad.
I bought 10,000,000 of these interstitial ads for around 1200 bux. I sent all of this traffic to my website that had adsense, with a the biggest adsense box, dead smack in the middle to attract "undue" attention to the ads.

I made aprox 2981.99 from adsense, now imagine if i had other offers on my page....This will not get your account banned, i have used this method for over 2 years now.

Imagine if i clicked some of those ads myself....

This system is extremely scalable and I was going to keep it to myself but I figured if I share a way that I know actually works, I hope someone else will share too.
