Seeing this also, but for me I see it across a range of IP addresses

Working as intended? i.e., site is being scanned perhaps for pages that could be vulnerable?

Thanks to Pippin (plugin developer) I have fixed this issue.

There was a conflict with the Divi Theme and its use of the Mailchimp API (Divi is a theme, not a plugin, so I was looking in the wrong place for a conflict).

Really responsive communications from the plugin developer.

The function in question looks like this

function ninja_forms_mc_get_merge_vars( $list_id = '' ) {

	if ( ! class_exists( 'Mailchimp' ) ) {
		require_once 'Mailchimp.php';
	}

	$options = get_option( 'ninja_forms_settings' );

	$verify_ssl = isset( $options['ninja_forms_mc_disable_ssl_verify'] ) ? false : true;

	$opts = array(
		'debug' => defined( 'WP_DEBUG' ) && WP_DEBUG,
		'ssl_verifypeer' => $verify_ssl,
	);

	$api  = new Mailchimp( trim( $options['ninja_forms_mc_api'] ), $opts );
	<line 345> $vars = $api->lists->mergeVars( array( $list_id ) );

	if( ! empty( $vars['data'][0] ) ) {

		return $vars['data'][0]['merge_vars'];

	}

	return false;
}
