Oh, as this bit of history has been questioned, I remembered something that always shows the history of a forum. As forum and rule structures generally and stubbornly remain unchanged for whatever reason on this dying site, there's always evidence here and there of rules that were put in place to discourage certain types of behavior that persisted in the past. And this forum is no exception.

This is definitely because people very much wanted to discuss prommies despite it not fitting within the content intended for this forum lol. Arguably the bits about "namedropping" and "anecdotes and personal experiences" may have also been prompted by this phenomenon, but I wouldn't say they're unique to this forum like the above is. And curiously the latter seems to not be enforced, since I can think of a few anecdote threads I've seen recently that do not belong here as detailed by the rules.
