I agree. Different communication mediums require different tactics. In the case of IRC though, I think it's due to a lack of good banning tools. One of the reasons I love Freenode is because they have good banning tools. For example, /mode #channel_under_attack +r will prevent people from joining if they aren't identified with nickserv. Once the attacker gets bored, you can remove the restriction.
