Dalyb, if it doesn't work for you it is most likely because of the 3rd party services we use. The code itself is clean and I've tried it over a hundred times (yes, you heard me, I've used my own faucet) with no duplication of the results you, Benil, niggtran, and kotwica666 are encountering.
Sorry to nitpick, but it says on the main page "You earn
0.0001000 per link viewed and there is no cooldown". But .0001 is 10000 sats, which is the withdraw limit, so shouldn't it be .00001000? If you're missing a zero from there, I wouldn't rule out the possibility that there's an important digit missing from somewhere in the code. It's not crediting for me either.
Oh crap, it should be 0.00001.
