Whenever you ignore someone, their messages sometimes disappear in the main chat. If you unignore them, their messages will reappear, but they will also still have the "Ignored" pawn in main chat. Their pawn will be normal in the userlist.
Alternatively, if their messages do not disappear, you'll be able to see their "Ignored" pawn in main chat. Once you unignore, the ignored pawn will still be there. However, their pawn will be normal in the userlist.
Note that once you click on the same user after unignoring, their pawn will go back to normal.
