Under Attack by Spammers

I’ve recently seen a sharp increase in spam comments which are getting past the Akismet filter. I may need to take defensive action if it keeps up, such as moderating comments or using some kind of CAPTCHA. Please let me know if you have any suggestions. I don’t like anything that impedes the flow of legitimate comments, but I imagine that spam comments are just as annoying to you as they are to me.

I know some people consider my roman numeral CAPTCHA annoying, but writing a semi-elaborate, custom CAPTCHA is what kept the spam away.

I still get some, but it is manually entered and low volume.

Maybe we should start competing for fun and original CAPTCHAs. What about a CAPTCHA workshop?


Well, the spam wave seems to have subsided for now, so I’ll hope it was just a freak occurrence. The roman numeral CAPTCHA is mildly annoying (I tend to cut and paste into a Google search to use their calculator), but obviously preferable to drowning in spam. I’ll take it one day at a time.

As for fun and original CAPTCHAs, this sounds like something Luis Von Ahn or his students might/should be working on. Not that more of us can’t play too.


Brian, thanks for the link! Of course, my more immediate mundane concern is how much that work has translated into easily installed WordPress plug-ins. But I’m intrigued by the research and will check it out.
