Let’s just suppose that there is a specific issue that it is verboten to mention on a specific Internet forum. Now the people who run the forum are entirely honest about why you can’t mention it. They are in a difficult position. They probably don’t like it any more than the users, but they have to enforce the rules.
Now, the users (for the most part) don’t mind too much about the issue itself, or the ban on mentioning it. But the issue itself becomes so intrusively irritating that loads of threads are started about it and ill feeling, thread closures and (no doubt) some ‘forum holidays’ are granted as a result.
Personally if I were in charge of the forum, I would see numerous, previously well behaved, forum users mentioning the unmentionable as a sign that the ‘issue’ is becoming more problematic.
Hypothetically. Of course.
