OP, can we get more context? Do you perhaps have more screenshot to share? The information we currently have here seems very limited.

From my previous attempt to understand the above-mentioned case better by creating an account there, all you need is a wallet. Perhaps you played from several wallet at once?
I could share more screenshots but it's literally the same stuff with their community managers on Telegram. They just say I broke the rules and it's a final decision and I'm not able to speak with the team that made this decision.
I did not play from several wallets at once, these guys are just scammers. I feel like an idiot at this point since they clearly advertise as decentralized but its not.
That was --IIRC-- my initial confusion on the older case too, about how they determine a multi-acc if they're offering a decentralized system. But I guess being decentralized doesn't necessarily translates to be full anonymous. They still collect some fingerprints.
Interestingly, I don't see any prohibition to create another account on their
TnC. I'll try to invite their representative here, but it might took a while for them to return, given they've been away for a while.
As you pointed out there are no rules against multi-accounting and the promote as a No KYC book.
