Personally, as long as they're upfront with how they handle things, I don't think it's a huge issue if a user accepts the terms. Sadly most casinos don't explicitly warn or tell users key details like KYC before they deposit so it complicates things. But yeah, only time will tell.
Honestly, if this casino proves to be reliable in the long term without being properly license, I still could see it being successful within the gambling community, specially those who are concerned with providing their person information to centralized entities and regulators.
Though, they must be very careful when comes to unpurposely providing liquidity money launderers and criminals with their casino, otherwise it could be just matter of time before their domain gets seized by either the European Union or the United States, in a similar manner to what happened to Chipmixer, even though the latter had nothing to do with gambling.
Also, this may be the first casino I have seen which openly claims to make their community to get involved with the resolution of conflicts between the house itself a other gamblers. In that sense, it is an innovation.
