Be careful of automated responses. What if someone spoofs IP's of legit users / customers / whatever and your automated response blocks them? Not good.
I thought about blocking....well, never mind - might pi$$ someone off and attract unwanted attention...

You might consider mod_security (/usr/ports/www/mod_security) which
can be set up to ban hosts based on behaviour or characteristics.
Or fail2ban (/usr/ports/security/py-fail2ban) is really great, too, in
that it scans whatever logs you want, and can trigger a block in your
firewall if enough violating log entries are found within a particular
period of time. Everything is totally configurable, and there are
plenty of examples that come with it.
