Plz accounts are accounts that are usually inactive and that are only used for their avatars. They have the same purpose as emoticons. Their usernames usually end with "plz," which means "please." Any deviantART member can post plz avatars in comments, forums, etc.
To post an avatar in a comment, put a colon, write the word icon, write the person's username, and then put another colon. Even if the username has capital letters, capitalization is not required in this type of coding. This
