Okay, so I did a test on my faucet for 1 hour, closely watching my google analytics as well.

Basically, I set the rewards to 1 satoshi and put a big mark saying 'If you're human do not claim from the faucet or you will be banned. Current reward- 1 satoshi'.

Below are the addresses which actually kept leeching on the faucet (and they can't even be tracked through google analytics)
