Hackers robbing and diverting referrals to their associates

I have noticed that I am getting a lot of referrals from some websites, and I am not getting any referrals at all from other websites though I am also sending a large amount of traffic. I think that Hackers are robbing and diverting referrals from some hardworking webmasters to their associates causing them great losses . Do you have a similar experience of referral robbery?

It depends on kind of clicking if it is PTC ads means normal getting even one million visitor whitout a single signup.

I am not sure how could anyone divert your traffic to his own website or links. can you please explain.
