Shadow banning is way of discreetly banning users, without their knowledge, in order to avoid instances of troublesome users coming back with new accounts. Shadow-banned users will be able to continue posting normally; however, their posts will not be visible to any other readers.
**Note: Shadow banning only affects a user's future comments, and does not work retroactively to hide their previous posts.
