The Flaws of the Honeypot Method for Spam Form fill Detection: CAPTCHA is Superior
It's quite unfortunate (and surprising) to still see users employing the honeypot method for distinguishing between spam and legitimate human form submissions.
For those unfamiliar, the honeypot method is a technique used to identify spam form submissions. It involves the addition of a hidden field, often referred to as a honeypot field, to the form.
The value of this hidden field is deliberately set to empty, and since this field is invisible to humans filling out the form, it will be submitted with an empty value in the genuine form posts. However, bots or spam agents filling out the form programmatically can see the honeypot field and fill it out like other fields. So in Marketo, when we see form fill-outs with the honeypot field "not empty," we know that it was a bot fill-out.
Unfortunately, this technique has an inherent flaw and isn’t an effective solution for catching bot submissions when compared to much better and more reliable alternatives like CAPTCHA.
For one thing, malicious actors can easily identify the honeypot requirements and bypass them by not filling out the honeypot field while making spam form submissions. As a result, these submissions appear valid, leading to an increased risk of spam form submissions infiltrating your database. To ensure better spam identification, it is highly recommended to utilize CAPTCHA instead.
The good news is that Marketo now offers native integration with Google reCAPTCHA v3, making it much simpler to set up than previously, which required setting up a webhook. By implementing Google reCAPTCHA v3, you can significantly enhance your spam form detection capabilities, as it utilizes advanced algorithms to analyze user behavior and identify suspicious activities.
TL;DR: The honeypot method is not effective in distinguishing between spam and genuine form submissions. Malicious actors can easily bypass honeypot requirements, making it unreliable. Instead, choose CAPTCHA for better and more reliable spam form fill detection.
