captcha scripts

[EchoFool]

I have been using captcha scripts for a while at moment, but what I would like to ask is, are there other ways to "log" activity of users that may be using automated scripts on my site, what relevant infomation could I log to check??

 

Also what are the best methods of making captcha's harder to get through, I know they are rarely 100% stoppable but there must be ways to increase the difficulty to the point they would not be bothered to try it ...

 

Thoughts/suggestions ?

I understand the need for CAPTCHAs in certain cases. But, if you are just trying to block bots from spamming your Contact Form, I would check out: http://www.modernblue.com/web-design-blog/fighting-spam-with-css/

 

I use it all the time, it is transparent to the user, and it stops 99% of the spam. I'll suffer through the 1 spam message a month that gets though to make the experience better for my user.

 

...although the more I mention it the less likely it will work

add filters to your images, where the text maybe swirls, has a drop shadow, or some sort of special effect. Do not use the "Basic CAPTCHA", where the text is the default GD text. Add some Lines, dots, wind, what ever you can to make it harder.
