		 The IRC spam bots that are successful in channels are a two part program. 
 
one bot idles in the channel, and when someone joins the channel it waits and messages another bot the nickname of the client that joined, that bot then messages the nickname that joined. (that way the bot isn't identified by it's nickname in a channel) 
 
The way people normally identify that however, is the idle time of the bot being reset everytime someone joins.
