Not completely true, I'm afraid. A few months ago, Kaneda went through a phase where he logged in, neg repped a few people, and logged back out. To combat this WW set his rep to zero - he could still neg rep people but it would have no effect (as long as it stayed at zero). It's now three, which means that a naughty member has given him +Rep.
The biggest loser is Kyeruu (64), who has received all of his rep through traditional means.
I'm surprised that Senesia has dropped to 96. Methinks someone neg repped her/him because none of us could, and still can't, work out whether s/he is male or female.
