I'm new in this niche, bought a faucet 2 weeks agoo and runned another one with my custom script!
But i have worked on internet more than 5 years, so i know when people send fake traffic! statistics are clear!

for a FaucetHub faucet it's impossible to get 17k unique visitors on mellowads without using ptc rotator and other ways, because u need to send at least the double of visitors to get this amount of unique! also the 600 clicks are fraudulent because are all unique!
I'm new but i know how traffic works!  

MellowAds is the bigget AdNetwork, that it's because they don't block these type of sites. they looks for money, and they pay according their daily pool!
Bitmedia have different rules, if you send low quality traffic they cannot convert it, so they ban people who send big amounts of low quality traffic!

If you advertise on PTCs by buying small amount of traffic, i think they don't ban u because a small amount don't afflict conversion!
