Here is an example of faucet abuse

John finally discovers crypto currencies, see a popular website, goes to the website makes the account and turns out he can't use it until he makes a deposit, he rather not make a deposit until he knows what dice is really about, since it might not to for him. He sees the faucet button and decides to try it out. He plays a few times with the faucet, gets hooked and immediately makes a bitcoin deposit. This is not faucet abuse.

Jake discovers a crypto website that has a faucet. He gets 100 VPN accounts and makes 100 accounts and writes a script which can automatically claim the faucet and make a bet. After a few minutes he finally wins big and makes the min withdraw. Then he keeps doing the same thing over and over again while making tons of money without having to make a single deposit and places tons of bets with no risk except for his time. This is faucet abuse.
