I recall a post years ago where we HAD to label vanity posts with “VANITY” just so you could see it, and avoid it.
And I would agree with that standing rule. It’s nice to have filter options for those who don’t want to participate. After all, they are just rants and/or opinion posts. But scrubbing them probably isn’t the best way to attract participation and paying members (outside the general rules of profanity, etc of course).
