I agree. Right now there is a smallish list of words that will cause a warning to pop up when they appear in short question titles . From Shog9's answer the regex is ^.{0,30}(^|\W)(anyone|difficult|doubt|easy|hard|help|interesting|please|problem|query|question|someone|stuck|very)(\W|$).{0,30}$ (Essentially a title containing at least one of the listed ...


proof-theory If your question is not about the area of mathematic logic called proof theory, do not use the proof-theory tag. Questions requesting proofs for a particular statement, or about how/why a particular proof of a statement works, should be tagged with the mathematical subject the statement lies in. This tag is almost universally used ...


Blacklisted tags I will start here list of blacklisted tags based on past discussions and information I was given by Arthur Fischer in chat. I made the post CW - it should be expanded if some new tags are blacklisted and if some other information can be added. math, mathematics See The "mathematics" tag. These tags are also intrinsic tags for ...


Sorry about the insane delay here. I wasn't aware of this post when the new tag creation warning was implemented. It is on for Math.SE now. Let me know if you see any weird behaviour.


linear-algebra Linear algebra is not algebra with functions such as $y=mx+b$; it works with vector spaces. Make sure your question involves vector spaces before using this tag. I've seen many new users use linear-algebra in place of algebra-precalculus.


algebraic-geometry Note that not every question involving algebra and geometry belongs in the subject of algebraic geometry. See the tag wiki if you are unsure. The tag wiki explicitely warns against abuse of this tag, and I've seen some incorrect use myself despite that.


probability-theory There are so many questions using this mark, but which are simple calculations for high school / undergraduate courses (and should use the probability tag). I've tried to edit these posts, but seeing that the same mistakes are made every day is a little disheartening.


differential-equations This tag is for ordinary differential equations. If your question is about partial differential equations use the pde tag instead. This is a common one and a simple warning as such would clear much confusion about the use of this tag especially for new users.


I have recently found a few questions tagged with functional-analysis which were just about the analysis of a specific function (or functions satisfying a certain relation like $f(x+y) = f(x)+f(y)$) and not related to actual functional analysis at all. I am not certain, however, if the problem is big enough to warrant an extra tag warning.


The notice is intended for future answerers to carefully check if what they plan to submit has already been posted. So all the more reason to have it implemented in big-list questions. I'm not sure what you mean by whether it is OK for a user to remove the notice as it is a pop-up that is meant to be removed after reading it.


Not seeing any objections, so I enabled the new tag creation warning here on meta as well.


I would advocate a warning for (or a name change) the tag complex geometry. This is supposed to refer to complex manifolds and complex algebraic geometry, but for a while the bulk of the posts were elementary questions about the complex plane such as one might find in precalculus or beginning undergraduate complex analysis. I suspect that changing the tag to ...


projective-space (Mixing roughly the structure of arjafi's text for proof-theory and the tag excerpt for projective-space) If your question is about projections in linear algebra (for example, projection matrices), please use the linear-transformations tag. Projective spaces are a subject of geometry that deals with spaces which can be seen as the set of ...


In general, I don't believe so - that is, I think in general the posting history of the user (including reputation and posting frequency) is not taken into account when deciding whether to show these popup messages. But things like the notification reminding you to vote on questions, which obviously would be meaningless if the user's voting history were not ...
