Posting etiquette is something that I never give any thought on this forum. On rare occasions, I see where someone posts a reply that seems to be a bit "short." I don't ever think any harm is meant. I'm pretty easy to get along with. I assume everyone I meet is honest and fair minded, and if they disappoint me, I move them to my "persona non grata" list. It's no big deal.
To me, ethics is a matter of not "going around someone's back." If you ask a question and get a good answer, then accept it and move forward, or NOTIFY the first person that you are seeking another opinion. I hate it when some of my clients shop my answers behind my back. It makes me think they are more interested in making me be wrong than in solving a problem.
I don't see the above on this forum.
