I am not sure if authorities are going to get involved
I have yet to see authorities involved in anything less than a case involving millions of dollars. Mt. Gox and Trendon Shavers are the only two cases that come to mind, and probably Cryptsy too. I seriously doubt any police action is going to happen due to a loan default on bitcointalk. I don't even think Master-P got prosecuted for his scam of thousands of dollars worth of bitcoin.
So no, nothing will likely happen if you somehow get your hands on an account that's defaulted on a loan. The account WILL get tagged if it's discovered that it's been sold, but the new owner isn't responsible for paying the loan back. There have been plenty of accounts taken as collateral and sold, and the debt just goes away. If it's a bought account, the new owner isn't responsible for that debt.
So bad, I hope that loan is connected with a person not with an account
Stop shitposting, even if it's your thread.
I think OP meant if the negative tag from the account will be cleared if he pays the loan back.
Ah, OK. My attention deficit is a nightmare.
