There are few (hmm.. many) proxy site owners who getting warned or banned from google adsense because of invalid clicks .. something a virus or .... Btw,To put a adsense in proxy you should put it in Main page not on proxified page. Rajat
You should wait a couple of weeks before putting adsense on your proxy. Its not because its not allowed (your allowed to put adsense on your proxy) its because there is a bot thats clicking on all your ads and google detects that as fraudulent clicks and you get banned. So wait a couple of weeks until everything is clear then you can put adsense on. - Prilep
