What they did is right, they make the guy exert a lot of effort first but he did not know that his efforts are only going to get wasted. Not familiar to the term Pandora faucet farming but faucet abuse is popular in every casinos so I do not think every casino can make an explanation to prove that they are right.
Well, What if I didn't claim the Faucet? Based on that guy, He made a deposit and he made it up to 6K+ to Doge. According to Casino Rules, He can withdraw if his minimum balance reaches $20 Worth of Doge. At first, Casino claims that the guy used a bot and they suspected bot activity on his account. Because he made some significant profit from a small deposit. I remember I made 60K Doge from only 48 Dogecoin and I played over a week to reach 60K Doge. That was on another casino. Back to the point again, After that, He made 2nd attempt and The Casino released his withdrawal. So he had a few Doge left. After he received his first withdrawal, He decided to withdraw the rest of the Doge too. And They confiscated the amount. You may want to read the accusation again.
