Your anti bot system won't protect you from any bots, hate to break it to you.
Well, I do agree that the "No bots" system is absolutely stone-age tech for anti-bots, but the reCAPTCHA should do the job.
reCaptcha definitely will not stop bots.
Better when you remove this "anti-bot system" - it will be better for users.
Atm only blocking IPs is good protection against bots.
Faucet is very clear, reward not bad. Good luck!
