Fighting Comment Spam with CAPTCHA

This weblog was experiencing lots of comment spam lately. So I've added comment verification image to the comment page. It is supposed to fight it back.


The solution is a CAPTCHA control for asp.net developed by Miguel Jimenez


It is a control combined with HttpHandler. You have to deploy dll to the bin directory, add path to HttpHandler in web.config, add the control to the page and you can say good bye to the comment spam. Sounds great. Subscribed.


Update: it is funny, but on blogs.msdn.com they went as far as comment moderation and disabling comments for old posts. Spam is good, moderation is bad :)


Update 2: And there are lots of blogs with disabled comments because of spam. I'm just watching now how spam comment fails in real time. I'm playing with CAPTCHA's code a bit and I'm preparing some improvements. Source code was not provided, BTW...
