I've seen this technique used before:
have a form with just a submit button in it stating something to the effect of "reveal email address". The form's action takes you to a server page that takes a querystring parameter, does a db lookup and retrieves said email address for display.
something like:
http://www.example.com/displayEmail/134
Of course... the obvious bugaboo with this page is that, if this page is linked somehow, how hard would it be to just increment the id in the querystring to get all of the email addresses in the system.... It would take a human to start it, but a bot could finish it. Then again, you could have the script accept a hash of the email's ID. Which would turn the above into:
http://www.example.com/displayEmail/02522a2b2726fb0a03bb19f2d8d9524d
and is obviously not incrementable...
Yeah, that might work. Should be accessible too... all you've got to do is click a button. Thoughts?

Without sounding completely dumb (i.e. I've not had time to read up on it yet) I would assume there's a reason these CAPTCHA test images are distorted instead of being plainly clear? Bots can read text inside images now can they? Little buggers...
I suppose spambots are a lot like internet porn always: always pushing the boundaries of internet technology to better enable their nefarious activities...
I personally can't stand those CAPTCHA thingies - as many have pointed out so far I find them nigh-on impossible to read a lot of the time - so some kind of text-based question would be a much better alternative and accessible too.
Anybody got any good references I can have a jolly good read? So far I've not been hit with loads of spam by having exposed mailto links and feedback forms (despite my advice the boss feels that forms and such will put off visitors to our site - a simple one-click approach is much more favourable) but it's something I'm pushing hard to implement.
