* This example 'guards' the channel against using abusive language. When
* someone says a bad word, it takes some action against him/her, taking
* in account the number of times the person uses it. The first time, it just
* warns the person through a private message, the second time it warns him
* publically in channel, and after the second time it will kicks the insolent
* out of the channel.
*
* To keep it simple, this example reacts only on 'fuck' word, however
* is is easy to add more.
*
* Features used:
* - nickname parsing;
* - handling 'channel' event to track the messages;
* - handling 'nick' event to track nickname changes;
* - generating channel and private messages, and kicking.
