captcha

Since I wrote about my sweary run-in with Captchas - those squiggly things at the bottom of forms that can only easily be read after too much coffee/beer - a week or so ago, I've been paying more attention to this technology.

Spam is still a pervasive issue and judging by a recent debate on the uk-netmarketing email discussion forum highlighted the problem isn't just a plague on inboxes, competition forms, surveys and any other web form is a target.
