A kick and ban does wonders too..
True, however, if they are slick(well, not really), they are going to go right to the nearest proxy and come right back to hound you. There are several ways to scan hosts attempting to access your IRC server for proxy use. Take a peek at bopm. This should help you out.

Also, SPAM bots will connect up and flood the piss out of you (along with skiz0rs). There are ways to club these idiots based on the amount of traffic they're sending to you. Again, the config for this varies so check out the docs to see how to throttle ban these irritants.
