Today I noticed that one of my questions ("How to check which command was used to load a .sty file?") was deleted. As the two consecutive downvotes, after nearly two months, without any explanation didn't help me to improve the question, could somebody please tell me what was wrong with that question.
It's been auto-deleted. The StackOverflow model is about having questions with answers. Questions which attract low interest, low up-voting and no up-voted answers are periodically removed from public view by the 'back end'.
Looking at the question, I don't think there's anything wrong with it, and I'm surprised it didn't attract an answer. I'll undelete and post something.
