My guess is that algorithmic checks are flagging posts and conservatives are interpreting that as censorship.
If you've seen the handy little graph of the first digit statistics that each candidate got in big cities, I dug into this a bit but the basic summary is precinct sizes aren't random at all and that messes up the entire premise of that analysis. I made a quick repo that altered the initial repo to show things like how just getting 70% of the vote would screw up benfords law in most counties [0].
There are some people who think it's a useful heuristic for uncovering potential oddities. Academics may not think so, but perhaps people who are professional analysts do.
Ultimately it comes down to who's side you want to take, and whether that's going to result in something akin to censorship.
Also, part of the reason I don't like commenting on any remotely political HN posts is that you get downvotes for saying perfectly reasonable things.
