OK but in both instances the Binance CEO gave well-explained reasons why the accounts were frozen and could provide evidence that they were connected to stolen coins. So I'm asking for somebody who works for Trade Satoshi to provide evidence of this or at least an official statement regarding this matter.

If the coins were connected to exchange hacks, there'd be no reason to address KYC issues -- the crime was already committed. KYC wouldn't make coins un-stolen. Without a statement from Trade Satoshi on the issue, it just looks like a reason to scam their customers.
