Comment:

 Hi @yogi5 and welcome to trac!

 This is already possible via filters available in WordPress. As most spam
 bots don't use the comment form, you would need to include code to prevent
 the comment from being submitted.

 As a very basic approach you could do something like this:

 {{{#!php
 <?php
 add_filter( 'comment_form_field_url', '__return_empty_string');

 add_filter( 'comment_form_field_cookies', function ( $value ) {

         if ( ! empty( $value ) ) {
                 $value = '<p class="comment-form-cookies-consent">
                 <input id="wp-comment-cookies-consent" name="wp-comment-
 cookies-consent" type="checkbox" value="yes" checked />
                 <label for="wp-comment-cookies-consent">' . __( 'Save my
 name and email in this browser for the next time I comment.', 'plugin-
 text-domain' ) . '</label></p>';
         }

         return $value;
 } );

 add_filter( 'preprocess_comment', function( $comment_data ) {
         if ( ! is_user_logged_in() && ! empty(
 $comment_data['comment_author_url'] ) ) {
                 wp_die( 'Error: Website URL field is not allowed.' );
         }

         return $comment_data;
 } );
 }}}

 As the feature is already possible via a plugin, I'm going to close this
 as unplanned.
