Filters messages out of the public chat (General, Trade, etc.) that contain key words or legendary items. The word list comes with pre-programmed words and can be edited. If you create a chat window named "spam" (without the quotes), blocked messages will be redirected to that window. Most brackets and symbols are used to define words with more flexible definitions (such as any length of "hahaha"). These symbols should not be used in words you add unless you know their proper use.
