Can we prevent titles with an unnecessary tag in them?
At present, there are a number of reasons why a question title may not be accepted. For example, when it contains the word "question", the post may not be submitted.
I propose adding the following validation rule to this facility:
X is any of the tags.
Or something like this.
It would hopefully stop people from repeatedly spamming us with redundant, unindexed, inconsistently-formatted pseudo-"tags" in titles. (And in case there's still any doubt about this subject, take a look at how SO renders HTML page titles according to tags, to see how it's designed to be used!)
