With my suggestion IMHO it would avoid the problem with those haters and would give any member the right to rate someone within 2 points, not more, not less. The votes would be tightly related to posts so the voted member would know which were his/her rated posts. The more people get to vote that member, the higher (or lower) the rating can get (which is very important, imo, to get a real impression out of a number).
What I forgot is that the number of members who voted someone must also be in the table (as it is now, btw).
And I corrected something in the other post: WDZ rates Tochjo positively (not negatively)
Well, I just thought it could help, nevertheless.
