Users are required to enter their phone number, date of birth, address in the profile page. Moreover, there is KYC requirement rules in the terms of your casino. Therefore, you shouldn't say that OLE777 is KYC free casino.
I guess what the OP was trying to say is that they don't require players to submit copies of their personal documents, address verification, and things like that. At least for now. But no matter what the casino admin says in this thread (that's his subjective opinion), if the terms and conditions mention that KYC might be required at any time, that's what people need to know and should focus on.
And regarding the personal information that needs to be entered at the profile page. That's not proper identity verification, and some players might consider adding fake information. They should think twice about doing that because it could be a road to disaster. Submitting fake information to the platform will be discovered if you are ever asked to conduct a real KYC verification. And then you are looking at things like account closures, seizures of money, having your wins voided, and stuff like that.
