I currently run a pay per download website using cpa-lead and one of my users always has a ratio of 90% - 99%, there was a time it was even 100% ratio he gets about 150+ leads on a daily basis. I asked him how he promotes his download links and he says he sends craigslist traffic to a facebook page but i'm not sure whether i should believe him. I suspect that he is botting the facebook offers because he only gets leads on two facebook offers. I have checked all the ips the offers came from and all of them are different maybe he's got loads of good proxies. What do you guys think?
