From my even more geriatric gen-x understanding: I’m guessing you are referring to /c/196 posts. Which has a single rule of having to post something if they visit the community. So people are titling “rule” because they are posting to follow the rule.

I ended up filtering that community out, because it was so much random noise when I’m trying to look at “all”

I like @misnina@lemmy.ml’s interpretation. But I had to comment on yours since mine is only 2 letters different. Though mine is pretty obvious where it came from :)
