I wouldn't count on that list. Just out of curiosity i checked poloniex that was listed as no-kyc, because i know they comply with regulators, like most of the CEXes in the world.
You can find poloniex requirements under:
3. REGISTRATION PROCESS; IDENTITY VERIFICATION
Where did you get this? I'm guessing it's either outdated or out of context
According from their help article, KYC is not mandatory
Q: What features and limits am I eligible for?
Our Level 1 account tier allows customers to access unlimited trading, unlimited deposits, $10,000 per day in withdrawals, and lending simply by entering their email address and password and verifying their email. For more information, please go here.
I'd say the list -- No-KYC exchange encyclopedia is for the most part reliable as it's personally checked. Updates are not real time of course but it's regular enough for most use cases. It's a good guide that cuts a good amount of steps when trying to research about a particular CEx. I've used it as a guide and then cross-checked with the picked exchange to be extra sure, it worked well.
