That just seems kind of ugly to me. But I do agree that the current system has at least one major problem -- the term "scammer" strongly connotes intentional fraud. But I think we all agree that a person who borrows some Bitcoins fully intending to pay them back but then can't pay them back (say they lost their job) deserves a scammer tag. The point is not to pass judgment or act like a court but to provide some kind of useful indication of who you cannot trust to keep agreements.

Honestly, I'd say getting rid of the scammer tag would be preferable to a plethora of tags. A broken trust indicator may be worse than none at all.
