(back at work and on a real key board now so I can do longer formed responses)
But this is also why we need the tools I'm building. What I'm talking about can only really be "witnessed", outside of anectdata, in the aggregate. If you wanted to help, I'm need to find specific instances of this happening and the Ozma one is low hanging fruit because the mod who did the ban said in precise language that it was being done in an effort to control the narrative (regardless of if you agree with the editorial bias or not, I think we take jordan at their word). Agreeing with the political bias of the ban, doesn't mean it wasn't an example of an authority (a mod) using that authority to structure the political narratives of the commons, which is what I'm trying to identify.
Specifically, there are a few mods who regularly were getting into flaming arguments which would result in them banning the counter party. flyingsquid was notorious for this, and its a task I need to do to validate a system for automatically identifying its occurrence. I need a couple real examples, so if you find any, send them my way. Some other good subs to look for are c/world and c/political_memes. Squid would regularly flame people then ban them.
And as far as "endless stream"; thanks, because that gave me another task to put on the to do list. What Ozma got banned for isn't actually what I'm really looking for (although it could be, but its beyond my original scope). What I'm really looking for are bans related to things that happen in the comments. But it would be important to getting a complete picture to also look at someones posts and maybe try and look at how that impacts narratives. That's a much more difficult process though, but I'm sure in review we'd get asked why we didn't do that.
