[thelist] CAPTCHA

[Barney Carroll]

I used to have a hidden input humanity test on my site's contact page. This
occasionally got blank emails through but never any spam. I have also used
simple maths (What's randomNumber + randomNumber?) with nothing getting
through, although this was on a very low-traffic site.
