I have uploaded HTTP:
roxyTest to CPAN.
http://search.cpan.org/perldoc?HTTP::ProxyTest
<quote README>
Robots that send comment spam are often hidden behind anonymous open
proxy servers. You can use HTTP:roxyTest to look for open proxies
on-the-fly and prevent such spam robots from submitting their crap. The
module is particularly useful if you don't want to bother your web site
visitors with CAPTCHAs etc.
HTTP:roxyTest tests certain ports of REMOTE_ADDR that are often used
for anonymous open proxies, and denies access if an open proxy is found,
i.e. it responds with status "403 Forbidden" and exits.

I have been using that approach to fighting comment spam for more than a
year, and it has proved to work well.

Your comments on both the usefulness of HTTP:roxyTest and the code
would be much welcome. Since the module source is conveniently available
at CPAN, I did not post it here.
