This content is 18 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.
A few months back I had to enable comment moderation on this site to deal with the blog spam I was getting. Unfortunately, over the last few days I’ve had to delete hundreds of spam comments sent to my e-mail for moderation so, with regret, I’ve had to turn on word verification to make sure that comments are only left by humans.
Please continue to leave comments on the blog – it’s always nice to hear when something was useful, or when someone has some additional information relating to one of my posts. I’m just sorry that I have to put these blocks in to make it harder for the ‘bots – unfortunately it also makes it harder for people to leave genuine comments too.
Since this site’s move to WordPress, I’m no longer using this solution – instead the Akismet plugin seems to be doing a very good job of managing my blog spam without the need for CAPTCHA-style word verification.
