Shadowban

A moderation state in which an account's posts are hidden from everyone else while appearing normal to the account's owner. Posts submit successfully, the profile loads, nothing is flagged, and nobody sees any of it. On Reddit the common triggers are posting the same link to several communities within 24 hours, posting at a rate that looks automated, and repeatedly linking to the same new domain. The reliable check is whether a post is visible in a logged-out browser.
