That is correct, the only way to measure for bad or fraudulent clicks is by averaging the percentage of what a normal click through rate versus one with fraudulent clicks. In order to protect advertisers investment we have to be aggressive with what we believe the acceptable click through rate is and if or when your traffic normalizes to what it is set to for the number of impressions expected you will get your payout.
Currently you are misleading customers promising "Currently you could earn 10.89 mBTC for one visitor" but telling nothing about CTR limits! It is really bad business practice!
