This is not the reason, if 1k satoshi is enough for them to live for a day, how did they afford to buy the computer that they are claiming satoshis on?
Public computer or they're hitching off someone else; however, that's not the point. I find it incredibly unbelievable that people can live off of literal pennies for an entire day; one thousand satoshi isn't even a cent.
Faucets are a great way for users to earn their first bitcoin, it's easy and even kind of fun.
Not really. It is impossibly hard to get a full bitcoin from fauceteering (otherwise everyone would be doing it), and I'm not sure what your definition of "fun" is but mine definitely isn't clicking through advertisements, hitting a button, and getting a pitiful amount.
