Be Gone, Comment Spam! (Again)

April 17th, 2005

I’ve had a lot of trouble with comment spam. This blog has blocked many thousands of comment spams. And unfortunately, it’s blocked a few of Cliff’s legitimate posts, too.

So I have switched to the new captcha module for Drupal. In case you don’t know, a captcha is an automated test designed to tell humans and computers apart. It often takes the form of a graphic with letters or numbers in it — letters or numbers than humans can read, but computers can’t.

I used this idea before with WordPress and it was 100% successful.

So now, you can prove that you are a human right when you make a post — and you will be told instantly if the post is accepted or not. And if it is, it appears instantly.

A lot of comment spam is arriving via trackbacks, and captchas can’t be used with them, so I’ve disabled trackbacks for now.

I think this should make blogging a lot less annoying.

This change also applies to the other Drupal sites hosted here: The Haskell Sequence, Forest of the Plains, and Rail Passenger.

    Blind people cannot read these images. Please also consider other alternatives

    That’s quite true. I do want to make my sites available to everyone: people with regular web browsers, text-only browsers, and text-to-speech readers.

    Unfortunately, I’m not aware of any alternatives, and especially not aware of any alternatives for Drupal. The Spam module I was running was just missing too many spams, and blocking too many legitimate posts.

    I’d very much like to know about alternatives; please send me any links you might have.

    In the meantime, I invite blind people to e-mail their comments or request for a user account to me at jgoerzen at complete dot org.

    Well, as you might have seen, captchas are gone from here now, sorry for the inconvenience.
