The FaucetBOX.com has nothing to do when a faucet sends you a referral payout or how much does it send. And it depends on the particular faucet when it'll do that. Faucet in a Box script requires you to manually request a payout, but some custom scripts don't. I'm not sure how Microfaucet works, I'd have to check that.
I'm sure Microwallet was the way I describe it and the same holds true for those faucets migrated to FaucetBox.
if ($row['referral_earnings'] >= 100000) {
$referralEarningsInSatoshi = (int) ($row['referral_earnings'] / 100);
$result = $microwallet->sendReferralEarnings($_COOKIE['r'], $referralEarningsInSatoshi);
if ($result['success']) {
$escapedReferralEarnings = mysqli_real_escape_string($db, $referralEarningsInSatoshi * 100);
mysqli_query($db, "update microfaucet_users set referral_earnings = referral_earnings - $escapedReferralEarnings where username = '$escapedR'");
}
}
Probably only the FaucetBOX faucets created from "scratch" exhibit this behavoiur (how sad!

)
I've sent you a PM about the balance

Thank you for your support!
