Could it be that the exchange is trying to get the stolen funds back from the money of people after taking some risks to make the money?
I don't think they are going to confiscate and steal customer funds worth $1.5 billion dollars, which is the amount they lost
to the hackers, in the largest crypto theft till date. However, i believe they have become stricter since the hack and they are going to confiscate funds for insignificant reasons to try and recoup as much money as possible.
