In general doing this manually would be folly but I know at least that there are efforts at blocking all "bad" bots (bots with recognisable user agents)
One example is: Apache Ultimate Bad Bot Blocker (find on github).
It uses BrowserMatchNoCase or similar to match user agents and put them in a list (set an environment variable for it) which then, as a whole, is denied.
There's little point in blocking known URLs your server doesn't have, as opposed to the bots that try to access the ones you *do* have.
So blocking the URLs is pointless (ineffective if you don't have them, and disruptive if you do have them), you will have to block the activity itself.
Many bots (most bots) do not actually identify as a common user agent, even the hacker-type bots will just use something recognisable.
Alternatively, when a known URL gets hit that requires password authentication fail2ban is often employed to block individual IPs.

DESCRIPTION
POE::Component::IRC::Qnet is an extension to POE::Component::IRC specifically for use on Quakenet <http://www.quakenet.org/>. See the
documentation for POE::Component::IRC for general usage. This document covers the extensions.
The module provides a number of additional commands for communicating with the Quakenet service bot Q.
METHODS
"service_bots"
The component will query Q its default name on Quakenet. If you wish to override these settings, use this method to configure them.
$irc->service_bots(QBOT => 'W@blah.network.net');
In most cases you shouldn't need to mess with these >;o)
INPUT
The Quakenet service bots accept input as PRIVMSG. This module provides a wrapper around the POE::Component::IRC "privmsg" command.
"qbot_*"
Send commands to the Q bot. Pass additional command parameters as arguments to the event.
$kernel->post ('my client' => qbot_auth => $q_user => $q_pass);
OUTPUT EVENTS
All output from the Quakenet service bots is sent as NOTICEs. Use "irc_notice" to trap these.
"irc_whois"
Has all the same hash keys in "ARG1" as POE::Component::IRC, with the addition of 'account', which contains the name of their Q auth
account, if they have authed, or a false value if they haven't.
BUGS
A few have turned up in the past and they are sure to again. Please use <http://rt.cpan.org/> to report any. Alternatively, email the
current maintainer.
