Since the episode with Eugine_Nier, I have received three private messages from different people asking me to investigate various cases of suspected mass downvoting. And to be quite honest, I don't want to deal with this. Eugine's case was relatively clear-cut, since he had engaged in systematic downvoting of a massive scale, but the new situations are a lot fuzzier and I'm not sure of what exactly the rules should be (what counts as a permitted use of the downvote system and what doesn't?).
At least one person has also privately contacted me and offered to carry out moderator duties if I don't want them, but even if I told them yes (on what basis? why them and not someone else?), I don't know what kind of policy I should tell them to enforce. I only happened to be appointed a moderator because I was in the list of top 10 posters at a particular time, and I don't feel like I should have any particular authority to make the rules. Nor do I feel like I have any good idea of what the rules should be, or who would be the right person to enforce them.
In any case, I don't want to be doing this job, nor do I particularly feel like being responsible for figuring out who should, or how, or what the heck. I've already started visiting LW less often because I dread having new investigation requests to deal with. So if you folks could be so kind as to figure it out without my involvement? If there's a clear consensus that someone in particular should deal with this, I can give them mod powers, or something.
Points 1 and 2 are reasonably clear. Point 3 is unhelpfully vague. If I were moderator, I would have no idea how far that pushes, and as a commenter I wouldn't have a lot of insight as to what to avoid.
I don't mind giving a catch-all authority to a moderator, but if there are specific things you have in mind that are to be avoided, it's probably better to enumerate them.
I would add an explicit "nothing illegal, nothing personally threatening" clause. Those haven't been problems, but it seems better to remind people and to make clear we all agree on that as a standard.
