Someone flagged this question as "rude or abusive".
It wasn't closed (but it was heavily downvoted) at the time. Should it be closed and/or deleted now?
If I am reluctant to delete it, it's mostly because it has an upvoted answer (i.e. people might think the answer is useful and should stay).
Another alternative would be to put a "historical lock" on the question, which would add this text:
This question exists because it has historical significance, but it is not considered a good, on-topic question for this site, so please do not use it as evidence that you can ask similar questions here. This question and its answers are frozen and cannot be changed.
A "historical lock" also makes it more difficult to find the question using searches.
- Leave it as-is?
- Edit the question, to make the question milder (e.g. to remove most of the criticism), but keep the answers on-topic?
- Leave as-is but add a historical lock?
- Close and delete the question and all its answers?
