Um, you do know faucets give coins away for free right? So how could this be a scam? There are any number of reasons the faucet may not pay you, but this does not fit into the scam category. You are out nothing if the faucet does not pay, so you cannot be scammed.
Yes we are out of time.
Also faucets run by revenues from advertisements so if we go to a faucet and use it then it's our right to get paid by them.
So faucets can also scam people, in my opinion.
