If this is not a trap why all posts similar to this issue are hidden and you can't see some posts of other customers from their Twitter you can only see them once you log in (Meaning it's not public).
And they don't announce publicly or notify their customers through PM about the changes in KYC requirements and TOS.
The usual behavior of centralized exchanges, they try not to spread information too much if it can cause a churn of customers. In this regard, OKX is no exception and uses the same techniques as other exchanges, such as Bitget, ByBit, etc. By the way, exchanges also do not spread information about improving their terms of service, for example, recently I accidentally saw that the MEXC exchange increased the limits for unverified users from 20
BTC to 50
BTC.
