View Full Version : Massive spam caused by javascript form.

Feb 23rd, 2012, 03:09 PM

We have a "Rate This Page" at the bottom of all of our website pages

The form was created with javascript and has an associated asp file. Can Captcha even be put into a form created strictly with javascript? It's gotten out-of-control....we're getting approximately 1 spam every minute.

I've attached Word docs with the code associated with the form. In every page is the following code:
[CODE] <a href="javascript:void(0);" onclick="sendFeedback(window.location);return false;">Rate This Page</a> [ICODE]

Thank you for any help you can give me, Elbee

Not sure but for this reason, and to just play around, I built a graphical jsCaptcha style element for forms. However I can't send it to you until later. It's on another sytem. If you'd like a copy just say so...;)

You can implement a simple but quite effective captcha with a basic question to which the correct answer must be given:-

What is 7 + 4?
Is the sky blue or green?

You can change the question every day, and obfuscate the answers so that a computer cannot read them.

You need to be aware that all captchas are vulnerable to real people in Bangladesh who are paid $0.01 each to submit the spam.
