I'd have to disagree with ya there Jugg.
From my own free sites, well over half my sales were from the warning page. That page is your first shot at convincing the surfer the paysite you're promoting has exactly what he's NEEDS
However, I do still treat it as a warning page. No hardcore images at all...not on banners...not on recips...none. Text is something else entirely...I'll get nasty in text...but no hardcore images.
If they dont' bite on the warning page...then I'll hit em with some hardcore images on the main page. Which by the way...is number 2 as far as where sales come from
