The banned users post states that posters are not banned lightly and a lot of discussion takes place prior to banning a poster. I know this is not always the case as I was banned within minutes of my post that got me banned. Clearly no such discussion took place prior to my banning as at most three mods would've seen my post. And a lot of discussion can't take place within the 5 minutes or so between my post and my ban.
So my question is do other mods review the reasons why a poster was banned after the fact? If so do they ever decide to overturn another mods decision to ban a poster? Have the mods ever discussed the idea of allowing the banned poster to appeal his ban?
Yes, they are reviewed. In some rare instances, they have been reversed. Yes, the banned poster can contact moderators. email@example.com
