If you remove their ads, and there are still inconveniences on the balance, then they ban you and tell you a story about an allegedly previously detected fraud. 

At the same time, the balance was calculated once a day, that is, they bought out the traffic they needed, even for pennies, but as soon as you stop driving traffic it, the alert arrives. 

In short, either they are petty offenders, or they are scammers. 

I was earlier 4 years ago, there was also an acc on the clickadile, and there were even 7 dollars left, I couldn't log in, the account was blocked. Apparently, they really are shaking for every penny. Poor people.
