Should an escrow be liable for any loss of such funds and get tagged till such a repayment is done?
Yes. Whether it's a third party escrow or the bounty manager himself, the liability falls to whoever holds the funds.
With that being said, I totally agree and understand if much of the users in this forum would paint my account red. I was too full of myself thinking the funds are safe sitting on a hotwallet. I should have known better than to trade the security of the funds for the convenience of using a hotwallet.
Oh yeah even Sam Bankman-Fried made similar statement during his interview with the investigators, that at the time in the operation of the FTX exchange, he got carried away and he lost touch with the ways funds were being moved in the exchange which lead to lost of billions of dollars investors money.
But that doesn't stop him from being held responsible for what happen, and in your own case too.
It's good you are accepting responsibility for your negligence in handling the campaign funds entrusted in you custody based on trust but at this point, the trust has been betrayed by what happened.
But what ever ways, you try to reach an agreement with the company team on repayment plans, because that is the honourable thing toe do right now in this situation.
