Hmm. I guess I can see where you're coming from, but I'd still disagree with banning all meta posts like that. But then, I moderate a much smaller subreddit, so I can afford some nuance. Back when I was mod at /r/NoStupidQuestions we relied on broad strokes as well--we had no choice, given the sheer volume of comments we had to go through. Thank you for not removing my post, despite my not checking with y'all first.

I usually leave these kinds of posts up so I can see people's responses. They are almost invariably mocked and downvoted to hell and the user slinks away shamefaced. On the rare occasion they are not, I learn something about my community. Feedback from users is invaluable.

That sounds like a great way to get yourself upgraded to a tempban to me.
