Freebitco has turned a lot of faucet users into gambler by displaying the "Multiply your bitcoins" pop-up message after each faucet roll. There were a lot of popular Bitcoin faucets in the past which was running the site by displaying Ads. Freebitco was doing the same thing, but they had discontinued the Ads by improving the betting section on the site. Freebitco was very much popular for faucet in the past, now it is more popular as a gambling site than faucet site.
the advertising feature is no longer available whereas before I was able to advertise there to get traffic from users, so far I think people are playing gambling because there are withdrawal limits that force people to gamble because it takes a long time to collect money from free rolls, there is another way to multiply money, namely betting and playing gambling
