I used to mod /c/Risa so I will back it up: this is exactly correct. There's a disconnect at the very heart of their approach to moderation they refuse to acknowledge. On the one hand, they want their written rules to be simple and common sense: be civil, don't be a bigot, don't spam, etc. etc. But at the same time, many of them have strong and specific opinions about moderation and/or Star Trek and they moderate to that effect. If you ask them about a removal which has tripped one of these hidden rules, at best they'll tell you it was covered under one of the generic rules like "no spam" or "stay on topic" and at worst they'll just start insulting you.

For example, one of the mods there is a huge Discovery fan and so if you say anything bad about Discovery without taking the praise sandwich approach to delivering it, it's gonna get removed and you might be banned. Anyone who tried to be critical of Discovery back on /r/StarTrek is likely familiar with this de facto policy. And of course, the mod who took over for me in /c/Risa is apparently not a fan of AI art or tabloid gossip and has banned these kinds of content, without changing my very simple declaration for the community: there are no real rules.

This exact kind of user revolt happened to them back on Reddit but between the fact that they were sitting on /r/startrek, the obvious place to have a Star Trek sub, and the fact that the most successful attempt at splintering was taken over by conservative dipshits almost immediately, /r/startrek continued to be the big main community on Reddit.

I'd love to see them develop an understanding of why hidden rules are bad for communities, but I don't see it happening any time soon. Looks like it's ales for everyone.
