Since some people spam the chat with unnecessary emoticons and other annoying phrases, I am sure it is time to add a little chat filter, to sort these things out a little. This plugin can also prevent hacks to be advertised by the user of the third-party tool (AKA the box), and can even execute commands on the players if they say a certain phrase.
The plugin may be outdated, but it really is worth a try in my opinion.
