I posted an answer to this question: Writing ads to attract female PhD candidates, which boiled down to "How do I write job ads to attract female PhD candidates".
My answer was as follows:
Don't bother trying. Your ad is unlikely to make a difference either way; in order to do a post-graduate degree in Computer Science, one would presumably need an undergraduate degree in Computer Science. Since men who complete said undergraduate degrees significantly outnumber the women who complete said degrees (and the ratio gets worse the more developed your nation is, as the women are more free to pick the jobs that interest them, rather than the jobs that might be more economically viable), the number of potential female applicants is already too small to make a significant difference.
It got upvoted up to +11 votes, and was then deleted by Wrzlprmft and StrongBad. Since there doesn't seem to be any method of privately messaging them on here that I can see, I have to ask them publicly like this instead.
When I click the Help Centre link, I get the following list of reasons for answers to be deleted:
- commentary on the question or other answers
- asking another, different question
- “thanks!” or “me too!” responses
- exact duplicates of other answers
- barely more than a link to an external site
- not even a partial answer to the actual question
My answer fell into none of those categories. As I said in the comments of that question to another user, "Don't bother trying" is a valid answer to "How do I [do thing]"; it conveys useful information to the person who asked that question (namely, that attempting to [do thing] is a waste of time and effort, and that they would be better off not attempting to [do thing]).
As far as I can see, neither of the moderators who deleted my answer even made any comments explaining what problems they had with it; they just unilaterally deleted it without explanation.
