How to combat spam, advertising, worms, virusses, drones
If your IRC network regularly receives spam and/or many (fake) users connecting, then:
 * 1) Check out Anti-flood features and in particular the sections there called DNS Blacklists and Connthrottle
 * 2) Use Spamfilter to kill / block people based on 'patterns' in messages or elsewhere. This is mainly against advertising/spam.
