I confirm that. I had 0.00069 BTC earned on my account there. This is more, than their threshold 0.0006. And I ordered a withdrawal. But today my withdrawal was rejected with no reason. Now they refreshed all to zero and all my earnings is gone. So, yes, it is scam, no doubt.
Hope you learned that faucets are now just a waste of time. Most of them will set absurd threshold level so you guys fail to reach it. They hope that you will give up soon. You are better off doing something else more efficient.
And this is not the right way to report a scam.
