The question Example of a metric space where diameter of a ball is not equal twice the radius was recently removed (around an hour ago). I noticed this because I had written an answer to the question, so I lost 80 reputation points.
I liked the question and I also put in effort in answering, so I was wondering if there is any way the post could be undeleted. Or, if there are good reasons for why the question was deleted then is it okay to ask what the reasons are?
