[thelist] Captcha??

[Flavia Tarzwell (FayeC)]

I have been asked to install captchas on 5 forms that are getting tons 
of injections daily.....
The issue is.......one of the sites is hosted in an IIS machine without 
PHP support and the captchas I found for ASP require files to be copied 
to the server's root folders.
Some hosts charge for installation and then monthly afterwards to have 
the files copied to the root folders.
So I am not looking for other options both easier to achieve and less 
expensive.
Can you recommend any other spam blocker or other captcha system I culd 
use?
4 forms are in PHP servers so it should be easier but I would also like 
to have other options since I have found information that points to 
captchas being both crackable and a road block for some people with 
disabilities which is a no-no.
Any advice, tips, information on the subject is appreciated.
Now back to googling.
