The cause for both of these is that my mobile HN experience is horrible for me (a lazy person).
I spent a few seconds looking for a word to replace "She/He", when none came to mind I fell back to a regular expression[1]. As iaml pointed out[2] (along with others) https://en.wikipedia.org/wiki/Singular_they is the proper solution to this issue, and I will try to remember that in the future.
In my second attempt at comedy today, Trying to perform the error-prone art of interpreting genders based on usernames, the best I came up with for you is
/^\0_$/
Feedback welcome, this is my first attempt at matching null in a regular expression.
I'll explain the joke, so that no-one feels left out: I interpret name "Void" as gender "null", then carry the underscore over, using artistic license, to make the regex more interesting.
