Just so you know, this is what you would do for PONG. That syntax isn't what you'd use for specific words or phrases. Depending what's appearing, there may be a variety of events and syntaxes needed. A couple possibilities depending on what you want to hide might include on RAW, on NOTICE, on SNOTICE, and on TEXT. There are others as well. So don't just replace "pong" with other words and expect it to work.
If you have anything else specific, post it and someone can tell you which event you need for it.
