Post History

This appears to be a data error related to imported questions.

The question was imported with four answers on 2020-05-04.  On 2021-03-02, a script deleted zero-score answers from accounts that were unclaimed -- that is, answers where the author never came and created an account here, and where nobody in the community here upvoted.

Deleting such posts was discussed in [this question](https://scientific-speculation.codidact.com/posts/280633), but I don't see any updates there about actions taken.  I'll need to check with the moderators to refresh my memory.

Is the question valuable?  (Y'all are the experts, not me.)
