I’ve had some time to chew on this - as well as consult the mod loop - over the last day or so. Forgive the delay.
The note is rescinded.
It has long been custom here to ‘invite someone to the Pit’ when one wishes to confront another poster with language and insults not suitable for Great Debates or other fora (though I’d be willing to bet the vast majority of such posts are in Great Debates). I have no wish to interfere with this custom. It provides a useful outlet and - hopefully - allows debates to continue without being sidetracked by invective.
However…
I can see a circumstance where such custom is exploited as a backdoor means of insulting other posters. Repeated instances of such or instances where the linked thread is nothing but an insult without further discussion could still be sanctionable by your friendly and tolerant moderators. The above examples do not constitute the entirety of posts on the subject that could result in notes or actions. If you find that vaguely defined then you are correct. I have no interest in trying to define bright lines here.
In short, use it in good health but don’t be a jerk about it.
