Of course not! Every word you write becomes my highly questionable intellectual property as soon as you hit the "Send It" button. I intend one day to publish several volumes of mindless drivel for the enjoyment of opium addicts and other select morons!
You could always just first if the question isn't already anonymous make it anonymous and then after that you can disvow it so you will never have to see it again even if someone ever answers or comments on it. Plus like I said you'll now be anonymous.
The problem is if they allow that then people will post all sorts of offensive questions and then delete them before the GAG admins see them allowing them to say and do what they want without getting punished for it.
Yes, that would be good but then don't you think over time users may start misusing that feature and posts will started getting chopped? I mean just like misusing any feature say down vote feature (which is now removed).
