not allow more than a specified number of submissions per IP address

[tertius]

I have a spammer attacking my ASP contact forms on my website. They're just a really basic ASP form using CDO. My host suggested that I redesign the forms to not allow more than a specified number of submissions per IP address. Does anyone know how to do that?

use an image captcha into your form. google "captcha"

captcha is only effective if you've got spammers that are spamming your site programmatically, however. If you've got spammers that are going in and manually submitting your forms.

You should also check and see if the CAPTCHA has a counter to block x number of wrong submitted CAPTCHA inputs. And have a redirect to set to take them to a diffrent page when it is reached.
