Comments and CAPTCHA

In my Using CAPTCHA for Comments post, I described the need to use CAPTCHA to help keep spam under control. Using CAPTCHA has dramatically reduced the amount of spam the blog is receiving and provides a nicer environment everyone. In a perfect world, I wouldn’t need CAPTCHA, but the spammers have other ideas. So, this is one of those situations where everyone has to pay for the misdeeds of the few and I truly am sorry I had to implement this solution.

Of course, anti-spam solutions are only good if they actually do the job. This solution does keep the spam under control and many readers have written to tell me that it works better than the CAPTCHA solutions used on other sites. I want things to be easy and workable for everyone. This solution also seems to be doing a better job of keeping the spammers at bay than other solutions I’ve tried, so it’s both easy and effective—a rare combination.

A reader mentioned yesterday that he couldn’t get the CAPTCHA I selected for the site to work. The CAPTCHA solution doesn’t want to accept the input he’s providing. What I’m trying to do at the moment is track down what is happening because I want everyone to be able to post comments as needed. If you’re having problems using the CAPTCHA on this blog, please let me know at

Please provide specifics on what you’re seeing to make it easier for me to hunt the problem down. If you could also let me know which OS and browser you’re using, that would be helpful. I need as much information as possible to determine whether I can fix the problem or whether I have to work with the CAPTCHA provider to fix it. I’m hoping the problem is limited to a few people and that there will be an easy fix, but I need good information to make this determination. Thanks, as always, for your help!
