I'm just tired of the signal pollution, and would like to be able to use karma to honestly appraise the worth of my articles and posts, without seeing 80% of my downvotes come in chunks that correspond precisely to how many posts I've made since the last massive downvote spree.
EDIT to add data points:
Spurious downvoting stopped soon after I named a particular individual (not ALL downvoting stopped, but the downvotes I got all seemed on-the-level.)
One block of potentially spurious downvoting occurred approximately one week ago, but then karma patterns returned to expected levels. I consider this block dubious, because it reasonably matches what I'd expect to see if someone noticed several of my posts together and disagreed with all of them, and did not match the usual pattern of starting with the earliest or latest post that I had made and downvoting everything (it downvoted all posts in a few threads, but not in other threads), so I'm just adding for completeness.
Spurious, indiscriminate downvoting started up again approximately half an hour ago on Sunday (12/1/2013), around noon MDT.
Edit: And now on Tuesday, 12/3/2013, at 10 AM, I'm watching my karma go down again... about 30 points so far.
Edit: And now on Saturday, 12/14/2013, at 2 PM, I'm watching my karma go down again... about 15 points so far, at a rate of about 1-2 points per second.
Are you frustrated because you want to see substantive and interesting posts in the discussion section, and not just meta issues? I think you have some common ground with ialdabaoth that you may be missing.
Here we have a valued and contributing member of the community who is frustrated with their recent experience and is reaching out to the rest of us for help. Your response sounds like a your-problem-is-not-a-problem solution. Couldn't someone make the same kind of reply to you? (e.g. "If you don't like meta-posts, just skip them. This one was even clearly labeled as meta!")
Currently, as far as I'm aware, LessWrong doesn't have any place other than Discussion to discuss meta issues. Perhaps one is needed?
