Items of information:
1.) There is no statistical data supporting the existence of more than the odd couple "troll voters" per challenge
2.) Those whos votes show a pattern of disruptive voting have their votes discarded. This is an automatic process that runs on the votes for every challenge.
3.) The voting follows a gaussian, e.g. "normal" statistical distribution, to a very close approximation, as one would expect, allowing for individual differences in voting strategy and opinion
4.) The average vote recorded for all challenges is very close to the center point (5.5) for the scale. It's actually almost precisely between the actual center point and the oft-assumed center point of 5.0, indicating that some folks vote 5 as average, and some a bit higher. Again, as expected.
5.) Anonymity affords the opportunity to "vote honestly" without fear of retribution for a low vote.
There is absolutely no justfication for a conclusion that DPC voting is unfair as it is; in fact, there is a tremendous amount of supporting evidence that it is very fair. Though there is certainly a very small amount of attempted manipulation, the effect of this is so small as to not be measurable. A move away from anonymity (even post-challenge) would put a heavy damper on truly honest voting, something that I personally don't think would be desirable at all.
