This post has been up for at least 7 hours now: https://docs.microsoft.com/answers/questions/856/paint-your-car-why-not-this-is-how-you-do-it.html. It's an obvious spam message, one which should have been deleted hours ago by your moderators.
Also, I could not find a report spam button in desktop at all. I found one by accident in mobile and reported it (also hours ago).
