The best way to stop the faucet abusers is to give the faucet only when the balance is NIL. In this way, a person cannot claim another faucet unless he has lost all the faucet amount in gambling and of course there is no way to withdraw the tiny faucet amount.
Not as simple as that, in fact most faucet on gambling sites are able to be claimed once user's balance is Zero but still there are many people who tried to abuse it.
Faucet abusers will keep on claiming the faucet only with no intentions to do real gambling by making deposit. Once they claim the faucet, they will use it to play, if lose then they will come back again.
They can create many accounts for faucet especially if the amount of the faucet is good enough. That's what we call with faucet abusers.
Didn't understand you. Even if they deposit, they will not be able to claim the faucet because their balance is not zero. If they keep on using the faucet money and losing it and reclaiming, there is nothing wrong in that as the money is returned to he casino.
Making multiple accounts is one thing which can be controlled by KYC or checking the IPs etc.
