Template:NoMoreCruft

Putting the following text into the Popular culture section of an article: Will show the following text (visible only while editing):

Purpose
The purpose of this template is to discourage crufters and inexperienced Wikipedians from adding pop culture triva. This template makes it easier to catch further cruft added to articles with this template as anonymous users tend to ignore it and blatantly add their cruft.

Template popularity
This template is a substituted template so the "What links here" option does not reflect the template's true popularity. Once a template is substituted, the result is no longer linked to the template, making it difficult to find all pages displaying that text (though categories can sometimes relieve this).
