google bans you very fast for invalid clicks. Keep this in mind. You know what is the main driving force behind adsense security? Conversions. This is the word. If your visitors do NOT convert, then google adsense will bust your ass, smartprice first and after that ban.No matter how many proxies you use. Whenever you hear stories about people who were COMPLETELY innocent and still got banned from adsense, this is not bullsh1t. The reasons they got banned is that their visitors did not convert. Simple as that. They might have been legit visitors, but if they do not convert, your ass is on fire. Keep this in mind whenever you want to cheat adsense. You can cheat and generate impressions, proxies, ctr you can bypass their algortihm. But there is one think you can not cheat. And this is conversions. If you send them crap traffic, they will bust your ass sooner or later.No matter if you have involved click fraud or not. That s why is almost impossible to cheat adsense.
Blackhatting adsense?
I exposed one way of blackhatting it using the referals scheme. There are other ways that involve increasing your ctr or increasing your cpc. But never invalid clicks. Google does not need to explain you why they ban. If they feel that you cheat them, the visitors do not convert, they will ban you, without even thinking to find how you generate invalid clicks.
Adsense is a business, and you have to play according to their rules.
