If a lot of people oppose this rule, either by downvotes and/or number of comments, I will willingly step down as moderator of this community.
I didn't see a large opposition to this rule which has now been deleted (see https://lemmygrad.ml/post/5220158), but I will pass the moderator position back to the instance admins nevertheless, specifically to @GrainEater@lemmygrad.ml who gave me the position when I requested it months ago. This post can be used to select new moderators by leaving a comment if you're interested. I will also take part in applying to become a mod.
