When I clicked on 'See Why', I was shown the following explanation
One can find Nextdoor's guideline on public shaming published here.
Did I violate the public shaming policy? I didn't intend to, but we all post under the moderated system. I want to particiapte in civil discourse and I think humor (my tongue-in-cheek drug habit comment) can be part of that. So I requested an appeal by using the 'Request an appeal' button. After submitting my appeal, my comment was listed as 'Under review'
After submitting the appeal, my comment was understandably still hidden and I waited. On Sept 11th I received a very brief notification in response to my appeal.
Hoping to learn more about why my appeal was rejected, I clicked on the notification only to see the following screen
I believe the entire thread was flagged and removed from Nextdoor. Unfortunately I wasn't given enough information to feel confident on how to craft future posts in compliance with the moderation guidelines.
Nextdoor's website and software does attempt to involve the community in its moderation system. Some community members have been invited to be members of the Review Team, but invitations appear to be random. The review team has at least some power to confirm and appeal flagged content. Anyone can flag content; however, it's still unclear to me if flagged content is always immediately hidden.
There is an explanation offered as to why content is flagged and, very usefully, a link to the guideline that was violated. Unfortunately, the appeals process does not offer much additional information.
I'm left with a handful of questions that I will continue to research
