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.
In that case, I need to be clear about probabilities.
I am pretty certain (p > ~0.97) that someone is doing this.
I have very strong suspicions (p > 0.75) that it's Eugine Nier, based on two reasonably strong facts:
The first instance of suspicious block downvoting happened within a few minutes after this spat - in which, I freely admit, I do NOT come out smelling like a rose. After that argument, I began noticing that EVERYTHING I posted was downvoted - and it has not stopped since.
about 80% of the block downvotes happen within a few minutes of him showing up in the 'recent posts' sideboard after his not having posted for a few days.
I can conceive of several alternate hypotheses, but none of them are particularly convincing in light of that pattern.
So, I made a hypothesis that turned out to be (barring very strange circumstances) uncomfortably correct. I'm currently going through this thread, trying to figure out how to update my entire social prediction and execution model - an aspect of my intelligence which has always suffered notorious levels of under-performance. Would anyone care to advise?
