I am talking about being publicly admonished by the site maintainers, not by other users. That gets done all the time.

The site maintainers don't come into threads and single out a specific poster for public admonishment. I've never seen it happen. If someone can point out any number of instances (because just one example does not a policy make--it just makes it an exception to the rule) to prove me wrong, I'm sure they will.
