UK. But it seems that what happened is not local, but for all accounts.
That's what I think is the reason why your account froze and ended up forcing you to verify KYC your country is one of the restricted/prohibited locations according to their terms. They don't even have an announcement or inform their customers that they are going to update their terms.
There are no traps there.
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.
