I am watching a site for last 3 months poping up adsense page. I heard that it is not allowed but if that then why adsense is doing noting except paying him
It's not allowed, you're right about that. Maybe AdSense don't know about this site - if you feel strongly you can report it.
I don't think premium publishers are even allowed popups... (just different "special" ad placements). But yes, it is against TOS.. just like placing adsense in a frame itself..
Okey here is url http://www.hotdate123.com/indian1/HRINDIANJFtest3.HTM Code (markup): you can note that this guy places ads like when this page popups noting can be seen except ads and header text is far away.
checked the page, didnt find any pop up, if u scroll down on that page u ll find the content. checked the page in firefox an ie but no popup appeared..
Adsense probably don't know about the site yet. However, if they do find out it will be banned most definately. It is not allowed by TOS.
