All of these mistakes re quite common in crypto newbie world besides faucets. I really do not think anyone sane uses faucets anymore besides people from third world where $1 means something.
On the other hand, these people re not targets for faucets marketing so it does not work.
$1 means something to the third world, all right. But if those third world people could go to work as a waiter, as stated in the article then, they could surely make more money then earning from the faucets.
