MATLAB: Deleted questions

meta

How often do questions with answers and comments get deleted? I don't mean double posts or spam or even questions no one has commented on or answered. I mean questions where effort has been put into answering them.
I don't search for my past answers all that often, but I find when I do, the questions are often deleted.
