GC28NB6 - B10: 100 DNF'S

A new one to the list and already interesting to note it seems this has more down votes than up
Can anyone who has down voted this one please explain why
For my twopennyworth (an old English phrase meaning my opinion or thoughts)
This challenge has criteria - log 100 DNFs - I know under current guidelines this negative criteria is not allowed - however this was placed in 2010, long before the guidelines and no different to all the other weird and wonderful challenge criteria that was put out then.

It didn't need 'Challenge' in the title
It didn't the attribute (though it has it now)
It has criteria

why is this not considered a challenge cache ?

Interested Tim

Hey, look at us agreeing on something for once. ;)

Since it only has two down-votes I would guess some people are still voting based on "does the cache follow the current guidelines" even though the information says that should not be relevant for the vote.
