A recent question focused on a certain term led to some confusion for those trying to answer it, as the way the term was used in the question made it unclear what the user was asking. The user replied to the comments on their post in a bit of a hostile manner since the term wasn't immediately understood by other users. The user then deleted their question(?) and rewrote it in the same manner they commented in with linked examples of the term to explain what they meant.
Now, I researched the term in order to find information that would help me in providing an answer, but I saw the user's original question also posted on Reddit. The same user's reply to answers there involved the phrase "those [*****] at stack exchange", etc., which struck me as incredibly rude.
I'd rather not name any names, which is why I was so vague, but my question is:
In a situation where a SE user publicly refers to other SE users (without their usernames directly involved) in a derogatory and harmful manner on a different website, is/should the user be subject to some kind of action here?
