Reported is an increasingly popular meme on Thaurissan Ghostlands Chat wherein users (usually with /dnd on, though the /dnd sect are calling themselves the DND Police and aggressively rejecting people not "given permission" to wear /dnd) yell REPORTED over General at other speakers for absurd reasons such as "reported for being reported" or "reported for breaking the silence".
Telling people that they have been reported has been a staple flamebait for some time. However, one user, as a form of lashback, began yelling REPORTED at users of Ghostlands general. Within hours, multiple users had begun to pick up on this meme, and developed the callsign of /dnd.
The DND Police are the sect started by the first disgruntled user of Reported, and are "invitation-based", though many others use /dnd "without permission" from the official sect. Generally, approval of /dnd is earned through a quick wit (not necessarily Reported), or simple fickleness of members of the DND Police.
As of this writing, there have been two confirmed instances of people actually being reported, and action being taken because of it.
