Just use play money or have some promos for your loyal members.
This is a good suggestion and might be a good alternative to fight those faucet abusers. If there's no choice, this could be the last option so these abusers will stopped what they do with the faucet abuse on mintdice.
On that note, I hope our rain platform is coming out soon, I've played with it on testnet a little so it's at least getting close but I can't quite give a launch date for it yet.
Also, a good option to use rains instead of faucets and hoping that no more abusing will be found.
Even so guys, this faucet abuse you're talking about there's no real benefit for players to use it other than just gaining insight about the games. So, even if there's a few people relying on the faucets the amounts are not enough to withdraw or play games where you can win for real money etc. And if the faucets are not built with these strategies in mind then rather than limiting the potential number of future customers by removing the faucets like you lot suggest which won't be sustainable not to mention that it won't look good on the casino, why not instead use the technology available to limit the power of the faucets in the way I mentioned above? This is something other casinos do btw
