Captcha Code on Landing Pages

We are using landing pages for several marketing programs and are receiveing alot of spam.

Id like to recommend that Captcha Code be adde to landing pages as it is to forms.

Thanks

I second this idea. I would like to provide contact details, perhaps a .vcf file - but only to visitors that knew the URL (e.g. from a QR code) and only if they confirmed being human through a captcha.
