CAPTCHA Requirement for Blog Comments

Posted by Kirby Turner on March 8, 2007

The number of spam messages received through blog comments at has increased to a point where I finally had to do something about it. So today I implemented a CAPTCHA field required to make a blog comment. The code is a partial C# port of the CAPTCHA Server Control for ASP.NET, which is written in VB.NET.

My next step will be removing the 400+ spam comments posted. Joy, joy.

Update: The CAPTCHA implementation has eliminated 100% of blog comment spam on this site. I wish email spam could be eliminated just as easily.
