I have an ordering form on my site in which the spam bots are having a fucking party. Captchas are not working (I think, anyway.) because the bots are bypassing that field, along with a couple of the other fields in the form. A human user cannot send the form without first filling out all the fields, boxes, but the spam bots can. How is this possible, and can those little automated pricks be stopped? Thanks. Perry
A common issue with Captchas are the way they are handled after input. For example, did you check that your script doesn't allow a valid Captcha, then allow you to simply refresh that page and re-submit it? If this is handled properly, you may need to generate a more secure Captcha. Jay
I agree with jayshah and in the short term rename you order form page - this will put the bots off till you implement a better Captcha.
I have written a blogpost about a more fun/useful method to stop spammers from using your forms, read it here. The major advantage of this method is that you won't have to annoy your poor users with captcha's and the like. If you'd like, I can help you implement a system like this
I'm having similar problems, Randombase, can you give me some indication how the js version of your algorithm would be implemented into the page? (sorry, i'm not great with javascript)
