CAPTCHA Anti spam v1
Because of accessability issues this mod is no longer being updated. please use the Gatekeeper mod instead
This mod may help prevent bots (web robots) from doing the following on your forum;
1. Registering accounts automatically
2. Posting link spam automatically
3. Emailing your members automatically
It does this by asking the user to read an image and type the characters into a textfield. The characters are designed so that a computer cannot work out what they are. This is called a CAPTCHA test - Completely Automated Public Turing test to tell Computers and Humans Apart. For more information on Captcha's see - http://www.captcha.net/
There are four captcha patterns included in the form of sub's; Grid, Lines, Circles and drawCode. If you wish to write new captcha patterns you will find the code in captcha.asp. Please share any patterns you create, the more patterns included the harder it will be for robots to crack.

one word of warning, this kind of Captcha does not comply with usability standards as visually impaired or colour blind users may have difficulty reading the letters<

Agreed. I use visual and audio captchas by using this - http://www.lanapsoft.com/ - Its fairly easy to implement, its cheap but not free.
If you only enable the captcha on post_info.asp then visually impaired people should never encounter it as its only shown to users who are not logged in.

I've seen problems in the PHP community, but has anyone really had bots register accounts on a Snitz forum?
BTW, here is a free version I came across awhile ago:

There is an application available ($199 retail) which automatically registers accounts and posts multiple messages. Its capable of automatically detecting whether the forum is phpBB, Invision Power Board or Snitz.<
