I got a couple spams through my Lime Daley contact form the last couple days, so I took another look at the script that I was using. I wrote it a year or two ago, and was my first attempt at writing an anti-spam tool that was designed to have a 0% false negative rate (ie. humans can't possibly fail - as opposed to the image recognizer thing, which I fail about 20% of the time, so I imagine less technical people people must fail and/or give up more often than that).
The one on the Lime Daley page isn't as good as the one I wrote for this blog, but I took a look at the statistics this morning, and it blocked 544 spams last month, only allowing three through. (More)
