Substack gives creators control of the conversation with Reply Rules

Substack is giving writers expanded control over their comments sections.

The paid newsletter website announced in a blog post on Wednesday that it is introducing a new system called Reply Rules. With Reply Rules, individual writers who open up comments underneath their posts can write out a quick summary of what they’d like to see from said comments. Anyone who wants to write a comment underneath a post, or in response to a Note or in Chat, will see these rules. Examples given included “no AI slop” or “stay on topic,” but theoretically, you could also ask people to exclusively reply in limerick form or something, if you felt like it.
