I created multiple accounts in the past and they recently implemented that your funds are locked
if your account is not verified.
Im in a mess because I used my ID already to verify my primary account.
Are you insinuating that having multiple accounts was not against the terms of service of the exchange when you opened these accounts? Which means it is the new policy that affected these accounts now. If having multiple accounts was acceptable before now, then you have a case. You could contact them and explain to them what happened. I am giving this suggestion because I am not comfortable with using someone else for verification, it could also lead to identity theft.
In addition to what has been said above, there's also a risk for you. What do you think would happen after someone helps you verify the account with their identity, lets you use it for some time, and then contacts the exchange and claims that their accounts have been compromised? it doesn't matter if you have access to the email and 2FA, he will be able to access the account again since he can always go through KYC again.
the accounts will be closed after they have been verified.
The OP claims that immediately after the verification and funds move, the account will be closed. Which means there is no fear of the person taking control of the account. However, this is a very risky option.
