When I right-click on a person's name in the chat window, I should have a Blacklist option. This would help to easily and quickly blacklist the gold farmers who spam the chat and tell windows.

As of now, I had to open my blacklist and remember the name of the farmer spamming because when I tried to scroll up in my chat window, when I switch back to type in the name, it auto scrolled me to the most recent chats.
