Looking similar to the ghost is the '''Unknown''' avatar. This represents non-realm ''Diablo II'' characters (open realm/single player), but is also used for any unknown client. This can result from a bad connection to Battle.net, logging on with an IRC-client, or various other connectivity issues.

Besides ''Diablo II'' characters, you may see other individuals in the chat channels. These other avatars indicate that the person controlling them is not logged onto Battle.net through the ''Diablo II'' client, but is a Blizzard employee, is using another Blizzard game, is logged on through a chat proxy, or simply has a bad connection.

Referees are individuals authorized to resolve disputes, and are often Blizzard employees or other officials involved in running tournaments or other sponsored events. They may or may not be using ''Diablo II'' as their client.
