I think this is a Scam. What are your thoughts? You Should Raise your Voice For These Innocent People's
It's a scam in my book:
Binance (as far as I know) doesn't require users to withdraw only to their own addresses. That would for instance make it impossible to transfer funds directly to another exchange. It's quite common practice for users to make a payment directly from an exchange or to another person. And on top of that, even if you owned the address, Binance doesn't require you to keep having access to the address you used 19 months ago.
Binance is acting like a bank here, and in this case you told your bank to pay a certain amount. If they repeat that same payment 19 months later, they can't hold you liable for it. What they should do is a big walk of shame for their own mistakes, and man up! They charge users 10 to 100 times more to withdraw than they pay on-chain, so it feels like karma if they now pay the price for being cheap on transaction fees.
TL;DR: Binance messed up and blames someone else.
Imagine you go to an ATM and take out $500. A year later, the same ATM spits out $100,000 when you're not around and the bank wants you to pay it back! That's basically what Binance is doing now.
