We have bots submitting directly to our Pardot form handlers. We were going to try implementing reCaptcha, but that won't work since they bypass our form altogether by scraping the DOM on our website. We had considered collecting the data ourselves and sending it to Pardot if it qualifies, but that won't work because we'd need to include Pardot Cookie hashes. Are native Pardot forms any better in preventing bots? if so, how?
