We tested this Bitcoin faucet in the period August 30th - September 2nd.
Even we tried to withdraw more times every day, the message was "insuficient funds".
Last time when we have claimed and tried to withdraw has been about 16 hours ago. Same "insuficient funds" message. At that moment, the account balance was 347 satoshi.
Now the balance is zero! The owner has deleted the earnings.
