This morning I was alerted to possible post voting abuse. I checked the logs and found what I believe is one member intentionally voting down another for no good reason (the posts in question where of a matter-of-fact nature, not inflammatory, and relevant to the discussion).
I was able to reverse the negative voting and issue a warning to the member in question.
Future occurrences of post voting abuse will result in a 2 week ban. This system was meant to dissuade overly negative or mean spirited posting only.
