Also it's hillarious that previous customers needs to identify themselves to get access to their funds. Lots of accounts are already verified. God knows where all the ID-papers are today...
I don't see why it is hilarious. How could the court return the spoils to the clients, without knowing who they are?
Asking them to sign a message with a known Bitcoin deposit address perhaps
If the court has access to the deposit logs in user accounts should be possible to get that done
