Strangely, this was working for me when I first implemented the code on my site. I just found this site, though, as I am looking for a new solution. For some reason… it no longer works.

What if I don't want to block a proxy server? I'd like to be able to use proxies so that my search engine won't jam no more. I'm referring, of course, to Google an their new Captcha policy. I'm working on a network with another 86 people so I always get asked if I'm human or not whatever I might be searching for. Any ideas?

A few years ago I looked for a good solution to block proxy servers. Also found that .htaccess solution, but as several state it is not working that well. Based on that I made my own solution, that I have now made available on its own website – take a look if you want. You can try it for free: http://www.blockthatproxy.com

There is a free membership available where you can try, also there is a page where you can test if it can detect the proxy server.

This is great to definitely block all comment spam!

I’m using it for some month now and it worked fine all the time, normal site visitors don’t seem to be affected.
Some of the previous posters wrote that it would not work.

Probably they tested the rules against anonymous web proxies but the rewrite rules do not work with anonymous. However, you should know that a comment spammer almost always uses transparent (not anonymous) proxies, they simply cannot use anonymous for some reason. So you should test your rules against transparent proxies and it will work if you’ve done it correctly.
