Well, on the internet I found this:
Google AdSense Leak - Pastebin.com
I’m surprised that it’s not already posted here. Anyway, I found that in 2012 Google done the same to Allen Wong - they took from him appx. $100.000 just before the payday (it’s in his book, as well as on his fanpage).
Anyone found similar situations with Google? If this will be true (and it appears to be so since Allen changed to iAds just because of that situation where they don’t wanted to pay his money) I think that AdMob is no more safe to use since any given moment You could be banned.
