I share your experience.... I had some banners made to advertise my referral link on other platforms and I am not getting "active" hits anymore... because they signup and try the faucets a couple of times and then they stop using the site. 

I should say that Freebitco.in should add more gambling games (Slots) to make it worth people's time to stay on the site. They decided to change their business model to a "gambling" site and have not done a full transition yet. (Adding Sports betting and Lotto etc.. is not 100% gambling)
