CAPTCHA Kinda Spam Prevention in ASP.NET

by JoeStagner 11/8/2007 4:39:57 AM

Spammers really bug me.

I've been working on this on-going sports related portal project (that probably will NEVER go live :)

I love of hobby community sites degrade quickly because they lack the moderation resources to keep the user submitted content quality high and I've been thinking about this problem.

I thought I would share some interesting links that I found on the subject.

Joe, you might want to look at this method blog.madskristensen.dk/.../...id-comment-spam.aspx

It uses an invisible CAPTCHA that also BlogEngine.NET uses and it just works. Since this was rolled out with the first version of BlogEngine.NET I haven't had a single automated spam comment on my blog ever since.
