The right response here is simply to ask for further substantiation, as danso did. It's not clear to me that the mods are directly responsible for what you've experienced. If you haven't, I would contact them for clarification.
Downvoting something for complaining about votes is fairly normal. Downvote baiting on top is flagworthy. I imagine lots of people quite sensibly apply these as a matter of course.
Suppose he is being treated unfairly by the mods. Is that not worth complaining about?
I don't give a crap about some silly "downvote every comment complaining about downvotes" rule. Complaining about downvotes was frowned upon because people get inexplicably downvoted as a matter of course here, and the frequency of complaints was deemed sufficiently detracting to warrant being frowned upon. Being treated unfairly by the mods, however, is another matter entirely.
I haven't seen a preponderance of evidence suggesting the complaint was ill-founded, and the guy's tenure and comment history (what I looked through of it) do not suggest he's an ill-mannered troll, so I reserve judgement as to whether the complaint is in the wrong. Like any reasonable person would.

It’s their site to do as they will, but it strikes me as interesting that they are held up as saints when they are anything but. Note that I’m not saying they are monsters either, but as someone on the receiving end of dang’s conduct I personally cannot agree with this post. It’s not like they are really accountable for their actions.
See that's where you lose me, I'm afraid. This is why it's vague to the point of being irrefutable.
I am somewhat rate limited it seems for reasons but I won't complain. I'm possibly more annoying than them.
