Just posting a funny link i found... http://www.webpagepros.net/google-adsense-size.html There's a "more sizes" link below them, dont bother clicking it though as you know the result.
OMG First off - his page is way into the gray area IMO for violating TOS as there is no "content" on the page .... Second - he's posting his pubid - the sad thing is, someone is likely to use it
And even more scary that he ranks #1 in google for the keywords "skyscraper adsense" Yea, if some n00b paste that example code into a webpage
But real question arised that, is that legal or unlegal, and why google not take action if he breaks the TOS. But really, I like this stupid idea for generating money.
He hasnt been reported yet I guess. Google takes 3-4 weeks so take action usually. You can surely try it out if you want to lose your account.
What he meant is the sample code, some n00b might guess that if he pasted that code into a webpage he could earn money.
