Here's my 2012 question. It also has 45 upvotes and 33 bookmarks:
Are there other kinds of bump functions than $e^\frac1{x^2-1}$?
Here's someone else's 2019 question that mine was closed as a duplicate of. It also has 2 upvotes and 1 bookmark:
Are there test functions $\in \mathcal{C}_{\text{c}}^{\infty}$ which aren't in the algebra generated by $f_{a,b}(x) := e^{\frac{C}{(x-a)(x-b)}}$
Between the closing of one of my more popular questions and the downvote I collected since this happened, I'm effectively being penalized for my participation. This has the effect you can predict on my motivation.
