Of course it could be a scam. What about sites that promise to pay newbies for clicking on ads and never pay them?
If you have to click on Ad's, to generate a income from the site, it's not a "faucet" site anymore. ^Grin^
A definition of a faucet, is a site, where people go to receive small amounts of currencies and in return they have to solve a captha to identify them as being human and not a bot. ^smile^
The site is full of shit, they do not know what a faucet is and how it generate and distribute money.
Some other articles from there have had obvious errors too.
