Academia - Is this kind of retaliatory behavior allowed? Is allowing it, in effect, discouraging questions?

I do not consider this answer acceptable because it violates be nice, in particular:

• Be welcoming, be patient, and assume good intentions.

• Don't be a jerk. These are just a few examples. If you see them, flag them: […] Harassment and bullying. If you see a hostile interaction, flag it.

Threatening or scaring users, in particular with consequences outside of this site, clearly violates this. This answer should be deleted as soon as possible.

Is allowing it, in effect, discouraging questions?

Sure, but there are far better reasons to delete this post.

The threats were inappropriate and definitely a violation of our be nice policy. I have deleted the answer. If a 10k+ user thinks they can salvage the answer, please edit and flag for attention so it can be undeleted.
