I was able to talk with Retz of Pinoy Big Blogger fame in the last Philippine BlogCon and he told me that he got banned from Adsense due to click fraud, or at least that’s what the Adsense Rep told him what happened.
In short, there was too much repetitive clicking happening on his ads. And that’s it — he lost his $1,200 to $1,400 monthly revenue from Google Adsense.
The unfortunate part was he never got an early warning. They just ban him immediately.
My theory was that some of his visitors got too click happy and it’s dependent on the niche you are into, showbiz being one of the most vulnerable to click happy visitors.
So, over-optimizing your ads could get you in to trouble, eh?
The next question would be — is there life after Adsense? 
We’ll talk about this on my next post. 
just to let you know that google has updated it adsense policy as of the 18/12/06 you can no longer have images next to your adsense
as this site is doing.
i did it with all my sites and it was great while it lasted. just thought i would tell you save someone trying to report you and get your adsense acount closed. here is the google source:

[...] Publishers as this seem to be a common practice in ad layouts. I earlier blogged about “Adsense over-optimization could lead to click fraud?” and this could be related to that [...]
Yuga, on my website, I placed an Adsense Link Ad right below an Adsense Image Ad for the post pages.
Do you see any problems with this? Does it violate the policies?
Thanks.
There are plenty of AdSense alternatives. For example, I highly recommend WidgetBucks. I’ve been earning almost twice as much with WidgetBucks compared to AdSense. Plus, the ads are optimized for WordPress, Blogger, and even TypePad. Check out this WidgetBucks review for some more info.
sort of enjoyed this post =) not all of it – there was some things which i found a tad off but overall it was a pleasant read, thank you for the post!
All the best, resor till korsika
