Also I think they can't handle the cheating issue anymore and they lose lots of money with it that's why they just choose to shut it down then focus on their freebitco.in.
A real human won't really waste their time to claim dust amount of money. The only way to make money from Freebitco's faucet and make it worthwhile, is to have lots of bots affiliated with each-other. I say affiliated both over real humans because it's impossible to have active real human affiliates because no one wastes their time into claiming dusts every one hour.
In the best case, Freebitco should remove their faucet and completely focus on rebranding. They should build a casino like Stake, Chips and others. The domain name won't be in touch with that but many of us know it because of their dice game, so I'm sure it will work.
