When you try to edit the tags when asking a question (or edit the tags of a question when having less than 2 k), a box how to tag appears on the right, showing some general help on tagging. The content of this box is site-specific, for example it is individualised on Anime & Manga.
Now, we have a handful of tags that are prone to being misused, namely phd, masters, thesis, research, publications, university, students, professors, conference and graduate-school. In fact I removed the research from what feels like 100 questions in the last months.
Would it be possible to add a paragraph or two to the how-to-tag help box warning users not to misuse these tags, do we actually want this and if yes, how should this help text be worded? With respect to the latter, you might want to cannibalise this help text I wrote on Welcome to Academia SE on the same topic.
