Why bother giving things to very small players? They won't bring much money anyway :/
It is not about profit all the time. Actually by giving freebies or even let them keep on using faucet, the site will be looking more crowded then the other site. Thus this will attract more players to come and stay, imagine how will it looks like when you are the only one play in the site . That is just so boring even when you are not chatting at all
