I've just checked the link you mentioned in OP. It is just a simple faucet with faucetbox API.
well. 0.001 BTC is nothing. but I can everyone can make a faucet himself by doing some basic research and by doing some extra investment to buy domain and hosting. but the full controls will be the owners's hand.
and in this offer . the OP will hold the control on your faucet as he is offering you subdomain from his own site.
For 0.001 BTC you get:
*A btc facet with faucetfly.com domain
*A page to manage your faucet
*I will teach how to earn money from the faucet with ads, affiliate programs, banners and others.
do you give adsense or earning from adsense also? I saw a adsense also showing in your faucetfly.com
