@Mary-joe I don’t think I’m famous, to be frightfully honest. You too could set up a blog which gets as much spam (but I guess you’re more interested in REAL traffic, like myself ;) ) as slightlymore. The answer is to write regular and relevant content, then the googlers (and indeed spammers) will arrive!

Good luck!

I’m not so sure about the numeric problems. JavaScript engines are perfectly capable of evaluating simple math problems, and even some more complex ones. This page gives a good demonstration of the eval() function in javascript.

Regardless, CAPTCHA’s that are image based are more likely to work, I’m surprised I haven’t seen a lot of bots get around the math problem.

Thanks for the comment Oli! Well, that’s what you get for not running Linux :p although I believe that there are similar technologies on IIS.

And onto THAT question – personally I think there are better ways to prevent spam than presenting the user with an unreadable, mangled word in an image. (for example, see the simple maths question on this comment form). One way that really gets me excited at the moment is adding an extra form field then, hiding it with CSS (obviously with a relevant descriptive comment for non css users) which is supposed to be submitted empty. Spambots will see it and naturally fill it in, so server side if the field has a value, it’s probably a spam submission.

Having said that, it’s not something I’ve done a lot of research into, so may well be flawed. Anyone tried this/know any more about it?

Interesting, although all the sites we do run on MS servers (I know I know!)

What are your thoughts on Captcha?
