Years have elapsed, from the link time period to now; what has happened with forum accounts isn't trackable based off of that. Here's another reason: simple privacy, next: I could also be implicating yet another innocent person just to satisfy your thirst for knowledge under guise that it "helps the investigation" and "helps get a repayment" - it won't.
This is a perfect example why account sales are terrible for the forum.
Account sellers/buyers and scammers don't get to use "privacy" as an excuse.
The "trivial to prove me wrong" statement is "guilty-until-proven-innocent"; not a great way, and not really supported in (normal) societies (apart from these cases where 'anything goes' because of the nature of BTC (I imagine?): accusations/allegations .. lead to this absurdity!).
Actually you've been proven guilty with the wallet links.
Just to be clear.. If there's an obvious way I can help, and I can conduct that help, - I will.
There is - repay the loans.
