Is there a way to add ReCaptcha or some other similar feature so that only genuine customers obtain a free digital download?

I have recently experienced 30+ spam downloads in the past couple of days, all with real-looking email addresses yet all with the first customer name of "James," and I need a way to stop this.  I temporarily password protected my downloads for a couple of days to stop the issue but that is not an ideal long-term solution.

This really seems like it should be a given as a feature but it seems that I cannot find it as part of any plugins anywhere (not even in security plugins, recaptcha plugins, or other download plugins... including this one that I've paid for.)

Help?

    Hi Bethany, I'm looking at adding an anti-spam protection method to the plugin at some point. For now you could add this custom snippet that performs the function. It will help to prevent bots from submitting download requests, using the "honey pot" method. Use a plugin called Code Snippets to add it to your website.

    add_action('somdn_before_form_inputs_simple', 'custom_somdn_output_honey_pot_antispam');
    add_action('somdn_before_form_inputs_variation', 'custom_somdn_output_honey_pot_antispam');
    function custom_somdn_output_honey_pot_antispam($product_id)
    {
    	echo '<div class="custom-somdn-download-form-website">';
    	echo '<input type="text" name="website" id="website" autocomplete="off" tabindex="-1">';
    	echo '</div>';
    }
    
    add_action('wp_footer', 'custom_somdn_hide_honey_pot_antispam');
    function custom_somdn_hide_honey_pot_antispam()
    {
    	echo '<style>.custom-somdn-download-form-website {display: none!important;}</style>';
    }
    
    add_filter('somdn_is_download_valid', 'custom_somdn_is_download_valid_honey_pot', 20, 2);
    function custom_somdn_is_download_valid_honey_pot($valid, $product_id)
    {
    	$honey_pot = sanitize_text_field($_REQUEST['website']);
    
    	if (!empty($honey_pot)) {
    		return false;
    	}
    
    	return $valid;
    }

    It's not a guarantee but should stop the majority of them.

    Thank you so much for this info and response.

    I was able to add a new snippet via the code snippets and copied/pasted what you provided.  That didn't work.  I also tried inputting my website specific information (domain, product ID) into the code you provided and it is not working, but I have no idea if I did that correctly or if I was even supposed to input any of that info.

    I am not sure what I'm doing wrong or if it simply is not compatible with my website.  I'm sorry I'm not more knowledgeable on any of this.

    If I was supposed to input my domain/product info, here is what I input with my domain specific information.

    add_action('somdn_before_form_inputs_simple', 'custom_somdn_output_honey_pot_antispam');
    add_action('somdn_before_form_inputs_variation', 'custom_somdn_output_honey_pot_antispam');
    function custom_somdn_output_honey_pot_antispam($product_37)
    {
    	echo '<div class="custom-somdn-download-form-website">';
    	echo '<input type="text" name="website" id="website" autocomplete="off" tabindex="-1">';
    	echo '</div>';
    }
    
    add_action('wp_footer', 'custom_somdn_hide_honey_pot_antispam');
    function custom_somdn_hide_honey_pot_antispam()
    {
    	echo '<style>.custom-somdn-download-form-website {display: none!important;}</style>';
    }
    
    add_filter('somdn_is_download_valid', 'custom_somdn_is_download_valid_honey_pot', 20, 2);
    function custom_somdn_is_download_valid_honey_pot($valid, $product_37)
    {
    	$honey_pot = sanitize_text_field($_REQUEST['ocrracers.com']);
    
    	if (!empty($honey_pot)) {
    		return false;
    	}
    
    	return $valid;
    }

    Thank you for your help.

    You don't need to customise the snippet Bethany, just paste the whole thing as is.

    Put it back the way I said and let me know when it's done. Post the website address here and I'll test the download form for you 🙂

    Okay, thank you.  I've copied/pasted and activated the snippet as you provided it.

    The domain is ocrracers.com and the form I'm concerned about is the free protocol test.

    Thank you again!

    I've checked the download and it is behaving as expected. This isn't bullet proof but should stop the majority of automated spam.

    Hi @rwebster

    If it will be available to add Recaptcha in the near future, would be great!

    I think it will not be very time-consuming. For WooCommerce there is a bit like a plugin that does Recaptcha on checkout. And if you look at it you will easily be able to perform. If so, I would use your plugin on many sites. 🙄

    I hope you add too.

    Thank you in advance.
