I saw many sites uses javascript (not popup)that the ads are jump once you load the page.. Example: http://www.file4save.com/477btf45yh5w/Asfur.S01E30.wWw.Asphur-Hot.Blogspot.Com.avi.html Is it allowed?
I think its not allowed that's the first time i've seen google ads like it. Better ask google about it before its too late.
You are not allowed to place the ads on top of your content. https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=105955
