How do you even appeal stuff like this?

It’s a literal brigade. They have subs that they post their sketchy propaganda-disguised-as news-articles to and then they all repost that content from other accounts. Because they are all mods, or have mods within the brigade, they can silence any dissenters, even people just asking questions like “what’s the source on this?,” or “that video didn’t show what’s claimed in the post title.” But it’s all agitprop.
