I searched for this question before after getting the message from a fautsy faucet, the Admin said he did not know.
So with my little search I found the answer.


After claim , there are a message that say "Unknown error." ?

It means , your BTC address is banned for our faucet , try changing to another BTC address or send a ticket (below) to see how we can help you.

So I got my answer and never went back to george faucet ever again, esp after me asking him a few times.

Link to where I found answer, site it finished btw
