Technically the faucet allows you to post. The satoshis are coming from tips.
How can use thos satoshis??
Good question. If you got enough tips you could potentially buy something from a merchant. Within memo you can use it to tip other users.
You should keep track of how much faucet funds someone used & if they get a tip then take half of it till they pay back the faucet. I'm half serious.
