You may not have sufficient privileges yet to see that the answer was converted to a comment by one of my fellow moderators, rather than deleted outright.
The content was preserved but since it is both phrased as question and a link-only-answer it is not a good answer.
Converting such low quality answers to comments is something only moderators can do and is something we regularly need to because new low-rep users are not yet granted the privilege to comment and are therefor required to post their suggestions as answers.
