Kiddies are DDoS'ing to annoy other users and to prove that they are capable of taking down the nodes.

All servers on the largest IRC networks are very well connected to the internet and servers that are not, wont be able to last long on these networks.

Some IRC servers wont allow you to create new IRC channels during a network split, so an attack where the network is being split constantly can cause quite a lot of annoyance for the rest of the users.
