I don't understand why people are marking perfectly good files as junk.

I think some may have completely misunderstood what a junkfile is. Just because someone has a hard time getting the file it isn't junk.

Like right now I am reeeaaally slowly downloading a perfectly good videofile. The best one out there for sure of it's kind (I have previewed it) and junkrating says 20%.

When I right-click it I can not mark it as not junk, only as junk.

Do people mark a file as junk just because it says awaiting sources for a few days or because they don't have the right codec to play it ?

I am sure that was not the intension of the programmers when they made it part of Limewire
