Long time ago I saw on some site how AdSense ad block was autorefreshing every minute without page refreshing, can anyone please help me to find this script?
This will be breaking adsense tos, don't do this and report the site you found ... this is a simple way that adsense can detect so fast ...
Yea its "illegal", but if you really wanted to know, they probably just put the adsense code in a frame along with those big keywords "Loans, CHeap Loans" etc.. and just used a meta refresh of around 30 seconds maybe.
