This question has been present on the site for several years, and the top answer has been there four years. I'm aware that it's first hand information, but it does provide useful information. I'm happy for people to doubt its credibility, but I see no way that not having useful information is an improvement on having useful information.
I also have references:

Can we put it back please?
