That's it. Our instance requires us to stop responding if you explicitly ask us to. It's right here buried in our Code of Conduct
Any discussions may be opted out of by disengaging.
In the past, this rule has only applied to the specific user you say it to. I'd like to suggest going forward that if someone on another instance uses it, we treat it as applying to all of us.
Unfortunately this rule wasn't communicated clearly before, so I'm making this post for visibility.
Edit: As the comments clarify, this has to be done in good faith, typically just a one word "disengage" comment. If you add more stuff to the discussion and then say "disengage" at the end, you're not disengaging, it's a way to put a stop to a toxic argument not to get the last word in.
I remember when the rule was created and I’ve seen it enforced plenty, also I think it’s a pretty good rule despite the fact that when it was new, somebody did the “write a huge wall of text comment and then put disengage at the end” to me and the mods actually warned me for not letting that person get the last word lol.
