Why was this question on the difference between take positions and take up positions deleted?
Because the deletion was done by a mod, raising the issue here is the only way to even have the possibility of re-opening what I think was probably the most interesting question to turn up all day!
Since asking here, I've realised that the deleted question was posed by a vexatious user (who's presumably been deleted again). But that doesn't make it a bad question. I've come in for some criticism in the past for re-posting a question under my own name (complete with my own answer) when a previous question from this user was deleted. Surely there's a better way to keep any reasonable questions from this tiresome user?
