Yes the system works fine, but that's not to say some don't abuse it
The "abuse" I recall of the karma system was to start pointless tit-for-tat puntering.
Three Nine can express what they think of others posting using the karma system just as others express what they think of their posts.
This has the potential to lead to said tit-for-tat, but checking the
last page or so of stats this doesn't appear to be the case as Three Nine's
dishing out (15 -ve/20 +ve on first page isn't that skewed I'd guess but would have to check others pages to see if it stands out) and
reception of karma isn't particularly heavy in a particular time frame if you look at the stats. So no tit-for-tat as far as I can see.
I suspect I'm missing the "abuse" you are referring to though.
Still a facetious and dumb comment to make about route setters though.
Anyway apologies
, I'm bored sat with nothing to do than drink beer and surf the net whilst waiting for an overnight bus.
