You can shut the service down. Today it is almost only used for IRC
In general identd reveals a lot of information to your system for the
hacker, for example which user runs a certain service, so it is a source
of information.

If you do have IRC users behind the firewall, then reject the packets
instead of denying them, otherwise big timeouts will occur, because no
packet is sent back, what tells the ircserver, there's no ident running.
