adsense based pages without content

I'm new to adsense. After a little research on how to make money with adsense i found a page(directory) based on adsense. There is no content at all in this directory. Every page in this directory has only links to related pages(in the same directory) and 3 adsense blocks. This directory is running for 4 months and has 1k-2k visitors daily. Isn't it violating adsense rules?

 

How do you know it's getting 1k-2k a day? Could you post it's URL please?

 

it has nedstatbasic counter
with publicaly available stats

 

just noticed, he has a little content text on each page at the bottom, but it has background color.

 

Google should not have problem about it. As it has some content. And its his trick to attrack visitors to click on those ads. I have also tried to publish adsense ads upfront on my blogs, and I do get more clicks for that. I have seen so many sites with very small content on pages and google ads upfront. Like infoscount.com .. its one of those sites, who earn a lot from adsense and spend a little lot on adwords. :-D and make money.

 

i understand the purpose of such sites, but he made content invisible(text color =background color). is it ok for google?

 

ohh no, no thats not acceptable... it inclines towards cheating..
