This is what I'd like to know. Based on mod comments in r/Toronto I suspect their regex is literally "ends with ?" and they have to manually approve every question.
They invented work for themselves that doesn't even need to exist and can be solved with the voting system. Every rule change they've made seems to be in an effort to make themselves relevant and take on unnecessary work. This seems like a common theme with Reddit moderators - they give themselves more work to do that nobody is asking them to do in order to justify their existence.
