My withdrawal was also cancelled.
I have used all mooncoin faucets for more than a year now, never got any problems. Also made many withdrawals and now from one day to the other I should have violated the terms and service.
I'm also just a normal user, no cheating or bots or whatever, visited the page a few times a day to claim, even do not have any referrals. I simply do not know what went wrong or how I should have violated the terms and also do not get any anwser from them. It's really annoying.
