Tons and tons of spam from contact form... How to increase security?

[AZColin]

We've had the shop live for 3 days and have received an insane amount of spam. I have the two options enabled but they are apparently very weak. My guess is this is yet another way for Shopify to make yet another app a necessity?

How can we make this more effective without doling out yet more money to a third party to provide something that should be a stock feature?

alienzero.bike is the domain

Here's the form:

<form method="post" action="/contact#ContactForm" id="ContactForm" accept-charset="UTF-8" class="isolate scroll-trigger animate--slide-in" data-cptcha="true" data-hcaptcha-bound="true"><input type="hidden" name="form_type" value="contact"><input type="hidden" name="utf8" value="✓"><div class="contact__fields">
        <div class="field">
          <input class="field__input" autocomplete="name" type="text" id="ContactForm-name" name="contact[Name]" value="" placeholder="Name">
          <label class="field__label" for="ContactForm-name">Name</label>
        </div>
        <div class="field field--with-error">
          <input autocomplete="email" type="email" id="ContactForm-email" class="field__input" name="contact[email]" spellcheck="false" autocapitalize="off" value="" aria-required="true" placeholder="Email">
          <label class="field__label" for="ContactForm-email">Email
            <span aria-hidden="true">*</span></label></div>
      </div>
      <div class="field">
        <input type="tel" id="ContactForm-phone" class="field__input" autocomplete="tel" name="contact[Phone number]" pattern="[0-9\-]*" value="" placeholder="Phone number">
        <label class="field__label" for="ContactForm-phone">Phone number</label>
      </div>
      <div class="field">
        <textarea rows="10" id="ContactForm-body" class="text-area field__input" name="contact[Comment]" placeholder="Comment"></textarea>
        <label class="form__label field__label" for="ContactForm-body">Comment</label>
      </div>
      <div class="contact__button">
        <button type="submit" class="button">
          Send
        </button>
      </div><div class="h-captcha" data-sitekey="f06e6c50-85a8-45c8-87d0-21a2b65856fe" data-size="invisible"><iframe aria-hidden="true" data-hcaptcha-widget-id="06lb2qmj9f0q" data-hcaptcha-response="" src="https://newassets.hcaptcha.com/captcha/v1/14dbe0f1619b8014e2630bcdde727e7785a80dee/static/hcaptcha.html#frame=checkbox-invisible" style="display: none;"></iframe><textarea id="h-captcha-response-06lb2qmj9f0q" name="h-captcha-response" style="display: none;"></textarea></div></form>

hi @AZColin 

Thanks for reaching out to the Shopify Community. I understand how frustrating it can be to deal with spam, especially just a few days after launching your store.

Since you already have the built-in spam protection enabled, here are a few additional steps you can try to reduce spam without relying on third-party apps:

Enable reCAPTCHA V3: Double-check if reCAPTCHA V3 is enabled in your Shopify admin under Settings > Customer accounts. This helps filter out bot submissions more effectively.

Restrict Form Submissions: If you're primarily receiving spam through the contact form, you can modify the form to only accept submissions from logged-in customers or add a hidden "honeypot" field to trap bots.

Block Specific IPs: If you notice spam coming from specific locations or IP addresses, you can block them using Shopify’s built-in security features.

Reduce Form Fields: Simplifying your form fields or requiring email verification before submission can help minimize bot submissions.

I see nowhere in Customer Accounts that references reCAPTCHA.

I've used honeypot fields before when hand coding PHP but checking that the field is filled or not requires form submission and I have yet found a way to view the full code (assuming it's PHP) to create that check. As a matter of fact, when I navigate to admin > pages > contact, that page appears to be blank so I can't even wrap the form in the {% - if customer -%} tags to require being logged in.

When I look at page.contact.json there's no form there to wrap.

When I look at contact-form.liquid I see the form inputs but don't see the opening or closing <form> tags to wrap.
