I think the scammer tag would only apply if the borrower and lenders didn't come together and agree on how to resolve the issue. If the lenders decided to take a cut on this and accept the borrower repaying a lower amount, that won't automatically make the borrower a scammer. Hopefully that will also incentivize the borrower to actually talk to the lenders, instead of just frieze up and try to disappear, which is a rather big problem out in the non-bitcoin lending world, too.
But he obviously hasn't thought of the risk of accepting bitcoins as a loan medium. I think that deserve some kinda of special tag, not knowing the risk is just as bad as scamming in my opinion. It also makes it unfair to people that actually did pay back their loans.
There's a right way and a wrong way to handle it if you get in over your head. If a borrower posts as says "look I fukked up, I'm sorry and can we please work something out" I got no problem with that. Doubling the duration of the loan or cutting the interest are possibilities. Just walking away is bs scammer behavior, but that's what most are doing.
