Accessible authentication codes

My friend Alan has just decided to introduce word verification on his blog, to prevent spam commenting. Word verification is when you’re forced to replicate an obfuscated in a textbox, in an attempt to ensure that you’re a human rather than a ‘bot. I was forced down the same route in July, 2005 when some comment spammers linked off to poker sites to elevate their search-engine rankings. The authentication plug-in did the trick in eliminating that pesky behaviour.

The lovely part about Alan’s implementation (a plug-in, no doubt, as I am confident that this is well outside his skill-set) is that it has an accessible alternative. If you click the disabled logo to the right of the textbox (not sure I approve of the logo), it reads out some numbers which you can then type into the box. Sweet!
