Support » Plugin: Contact Form 7 » False positives/negatives with reCAPTCHA v3

  • Resolved m53rd


    With reCAPTCHA v3, we get a fair amount of false negatives (spam emails getting through). We also have one form in particular that seems to trigger a lot of false positives. This is our Suggestion for Purchase form, liked to above. I realize a form with a request to go buy something probably sounds pretty spammy, but we need to know what our readers want to read. The form configuration is as follows:

    <p> </p>
    <p>Your Name*<br />
    [text* your-name] </p>

    <p> </p>
    <p>Library Card Number*<br />
    [number* Library-Card] </p>

    <p> </p>
    <p>Email Address* <i>If you do not have e-mail access, please leave this space blank.</i><br />
    [email your-email] </p>

    <p> </p>
    <p>Phone Number*<br />
    [tel phone-number] </p>

    <p> </p>
    <p>Select Library Location for Pickup*<br />
    [select Location include_blank “Central” “Ashwaubenon” “Denmark” “East” “Kress (De Pere)” “Pulaski” ” Southwest” “Weyers-Hilliard (Howard)” “Wrightstown”] </p>

    <p> </p>
    <p>Title*<br />
    [text* title]</p>

    <p> </p>
    <p>Author*<br />
    [text* author]</p>

    <p> </p>
    <p>Publisher<br />
    [text publisher]</p>

    <p> </p>
    <p>Publication Date*<br />
    [text* publication-date]</p>

    <p> </p>
    <p>ISBN<br />
    [text ISBN]</p>

    <p> </p>
    <p>Price<br />
    [text price]</p>

    <p> </p>
    <p>Format<br />
    [select Format “Book” “Large Print Book” “Magazine/Journal” “CD” “DVD” “Audiobook” “Newspaper” “Other”]</p>

    <p>What is the subject of the item? (example: true crime, gardening, education, etc.) Why do you think the item should be added to the library collection?<br />
    [textarea Subject]</p>

    <p> </p>
    <p>Interloan<br />
    [radio Interloan “Yes” “No”]</p>

    <p> </p>
    <p> </p>
    <p>[submit “Send”]</p>

    And these values seem to trip it up the first time. If you hit submit right away again, it works.

    Any help would be appreciated. I understand the desire to move to the new and get rid of the old, but reCAPTCHA v2 was working quite well for us.

  • The following is very likely to look spammy in any form submit:


    You might want to try Contact Form 7 – reCaptcha v2 in addition to Contact Form 7. Once installed and configured it offers the same reCaptcha functionality you are used to in previous versions of Contact Form 7 (recommended by CF7 plugin author).



    I really appreciate the tip! I certainly understand why the amazon link would look spammy. Unfortunately, this form encourages that sort of input because we’re literally asking our customer to tell us what to buy. I installed the plug-in that you suggested, and we’re back in business. Awesome!
