Yes I did that immediately. I don’t know in this case if the inclusion of captcha would be useful or simply a nuisance to legitimate users. I’ve had a few experiences lately where the captcha image has been so illegible that it was downright infuriating.

That’s why Tim uses something far more subtle – a honeypot. Regular users don’t see it, bots do see it and have no brain to figure out that they shouldn’t fill it in. If a form is submitted that contains a value in the honeypot field, then the script treats it like a banned address: sends them straight to the success page, and sends their spammy mail to /dev/null.

Yes it’s certainly a more elegant solution than the captcha images, which are often defeated quite easily by the bots anyway.

Neither a honeypot nor a CAPTCHA will defeat the “room full of bored humans” attack, which is staggeringly inexpensive to mount in less enlightened nations around the globe.

It goes without saying I’ll be getting a certain amount of spam one way or another before long but I use SpamAssassin on the server and I have SpamSieve on the computer, so you do what you can though I still find it staggering that nobody has yet come up with a more concrete solution to minimise the amount of spam that is sent.
It really gets my blood boiling when spammers use your email in the From field and you end up getting bombarded with failed delivery messages. To an extent using DKIM and SPF helps limit that if it’s set up properly. People should also avoid using catch-all email
