(PieFed also has a feature called ‘Topics’, which aggregates posts from multiple communities into a single feed around a single theme, making jurisdiction a truly joyful mess: a single post can be made by someone on server A, posted into a community hosted on server B, and then aggregated into a Topic hosted on server C. What happens when rules between servers A, B and C conflict is anyone’s guess.)

Well, i think they don’t understand what is a topic (multicommunity) or how we handle the moderation part. 🤔

We moderate per community and its own instance first. So we don’t moderate post outside our instance unless we receive recuring repport. And if a post in a community that appear topic contrevene instance’s rule, we delete it or remove community.

It may be complicated the first time you moderate but it’s easy once you understand.
