I think there is someone sending bot to claim at my faucet take a look at this

I have the same problem too with my faucet. Somebody (of course and like always) from Russia is claiming 24/7.
I still don't find how he's proceeding so I can close the gap.
I don't even know if we are talking about the same user. For me, the problematic address is 1FEKdLcjycR1HaZrXrp5WSg2M5oLm3UHmU
I finished by just blocking him, but would like to discover this hole in Alphafaucet so it can be mitigated.
EDIT : Strange thing is that the address I'm talking about is claiming continuously from various popular faucet scripts/templates, not specifically AlphaFaucet.
