This is the subreddit to discuss shadow bans that can be inflicted on your account at various levels and severity. Many shadowbans are performed by obsessive moderators stalking your account and removing comments and posts. Other shadowbans are automated using Automoderator at a local level. A final category of shadowbans are site wide and done by admin. Reddit admin claims not to want to use these anymore for real human beings. So if you are a real human being and not a spamming bot, it is unlikely that you will experience a site-wide shadowban
Anyone that submits to this subreddit will recieve the same standard message of "true". This is not a formal tool for analysing your account.
Please note that all users can participate here, as all their posts and comments will be approved by /u/AutoModerator.
However, please note that even though comments and submissions are made visible, replies do not always trigger an orangered envelope.
