How often do you see your leads revoked?

As the title says, how often do you see your leads revoked? I started using AWM and so far I have very very little traffic that gives me 1-3 leads a day, but today I saw that one of my leads has been removed. Does this happen often? I wouldn't expect that with so few leads (which are legit) that I receive.

You never can be sure that your leads are legit, someone may have completed an offer for you but used totally fake information - the advertiser can't monetize fake informations and therefore isn't going to pay for it. I own a network and I see leads reversed all the time, especially because we mainly deal with incentive. That's just the way it is.

You can increase the quality by pre-quaifying them. Also dont use incentive traffic as the quality will be shity most of the time.
