This is a question with a duplicate title to (dis-)prove a point made here:

"there is no need at all for [the title] to be unique" Except that the Stack Exchange software requires it. – svick

The title is shared by How can we avoid redundant titles?

This was made possible by adding extra spaces to the title. They are used for the uniqueness comparison, but get stripped out later.
