Hi, I heard that if you have an adsense account in india and earn too high, adsense will ban you suspecting blackhat and fraud, Is this true?
You'll get banned only if google discovered you have done any fraud or broken their adsense policies.
Adsense prefers high earning legitimate publishers. Why should they ban them? they takes 32% of what publishers website makes.
Why Google ban you if you use Adsense account properly? I don't think so if Google allows you to place ads both you and Google gets benefit. Lot of if Indian Bloggers earns tons of dollars per month through Google Adsense. Perfect example is Amit Agrawal and his Blog Digital Inspiration.
