The OP has researched on faucet and has a good definition about faucet on his post, but I wonder why still suggesting it to -Newbies- I have heard people thinking crypto-currency is a scam after accumulating coins from faucet that was miserable/small and they restricted them from withdrawing it.
If a legit site is used, there should not be a problem but there are some sites that might be fake, I did not go more into faucet in the past, but I know some cloud mining are fake, also very possible there are fake faucets, some might be used to scam newbies very possible because it it is newbies that make use of faucets, but later got discouraged after seeing it as a waste of time.
And I would not think the love for free Bitcoin like faucet, is what encourages Ponzi schemes in crypto-currency, scam give away.
I do not think so too, such scam like this is just because newbies do not know much about crypto an no nothing about scam yet, greed is the other reason people get successfully scammed.
It is important to keep in mind that a lot of the popular faucets are not really faucets at all but are just gambling websites offering a chance to win free Bitcoin.
Just like freebitco which is recommendable, not for the faucet because faucet is just a waste of time but for gambling and having good reputation.
