It's a good idea, but i think it's will be hard for faucet owner because most of them run faucet with very little BTC, and they don't want to spend any money. Scammers can scam you in many way, not only on this forum.
I understand. But if a small fee compared to their faucet scale. If they did not introduce it here, they would find it a bit difficult to advertise it extensively and quickly. Or they will lose some advertising costs. But advertising fees here will not go away if what they say is true.
