113 is ident, it returns the user name owning the outgoing
connection.  its used by irc servers to get your username.  many sites
make ident queries.  its useful if you have users in that if one of
them causes problems somewhere you can ask for ident results to find
out who the troublemaker is.  

if you block it you will be denied access to many irc servers.
