CAPTCHA

I’ve installed a new Movable Type plugin called Scode – this enables me to add a CAPTCHA to each entry. This means that I now have an extra layer of spam protection. Anyone leaving a comment now has to enter a security code before the message will be accepted – scripted spam bots will not be able to read this extra field and so I’ll have fewer junk comments to clear out every day.

I know there are accessibility issues with this, so I apologise if anyone with a screen-reader or other partially-sighted people find it difficult to leave a message. My site statistics haven’t revealed much screen-reader activity so I’m hoping that this won’t be a problem at all. Plus, I don’t get a massive number of comments anyway – sorry to those that do leave one. I hope it’s not going to put you off leaving little insults as usual!

There are a couple of issues that I’m already aware of. The error message that it gives you when you don’t enter a security code is a bit shite – I need to work on that. Plus, this won’t work on Trackback spam, and I get more of that than anything else. Most of the anti-trackback stuff I have installed just moves the spam into a junk folder – I still have to go through it every so often just in case I have a false positive. I get hundreds of spam trackbacks every week – they’re a pain in the arse, but at least they’re not getting published.

Still, thanks to Arvind for putting this plugin out there. I’ll give it a go and see how it works for me.

    Sorry, your feed only provides summaries so hadn’t seen the rest before commenting. You’re already aware of the accessibility issue with captchas, so just look on the previous link as further background.

    This one is interesting and discusses possible alternatives: http://www.standards-schmandards.com/index.php?2005/01/01/11-captcha
