There is no point in discussing it in that reddit page anymore since faucet bot has been banned by stunna and perhaps they will continue to do so in the future so its kinda pointless
Its from a PD mod. And more importantly I don't believe human captcha solving will be discouraged, and the script is just to show how much time you have until next faucet payout.
It'd helpful to know how Stunna is deciding which are bots and which are people just anxious to claim that they time it correctly.
