In order to maintain your access to Nextdoor you must never share an opinion that disagrees with others. Those that manage the site are not objective. The "Leads" are bias and often look the other way as they frown upon comments that show personal opinions. The "Leads" support those that complain about others regardless of any content posted. Those that report others for comments not appreciated are never exposed or made known so a person who is flagged for any comment is always found to be wrong, regardless of content of the shared post. Many people are flagged by others based upon personal dislikes rather than content of a post.
If you do not like somebody on Nextdoor then all that needs to be done is to flag them and they will be disciplined or suspended without just cause other than they were flagged.
Nextdoor is a site that has the potential to be very good, but all too often politics and liberalism set the stage to prevent this site from being more than what it currently is... a site run by closed minded people with no objectivity towards fairness.
