Answer 1

To remove any field you should pass the $args of which fields you want to be showed in your form.

Exemple:

<?php
    $args = array(
        'fields' =>array(
            'author' => '<p class="comment-form-author">' . '<label for="author">' . __( 'Name' ) . '</label> ' . ( $req ? '<span class="required">*</span>' : '' ) . '<input id="author" name="author" type="text" value="' . esc_attr( $commenter['comment_author'] ) . '" size="30"' . $aria_req . ' /></p>',
            'email' => '<p class="comment-form-email"><label for="email">' . __( 'Email' ) . '</label> ' . ( $req ? '<span class="required">*</span>' : '' ) . '<input id="email" name="email" type="text" value="' . esc_attr(  $commenter['comment_author_email'] ) . '" size="30"' . $aria_req . ' /></p>',
            // 'url' => '<p class="comment-form-url"><label for="url">' . __( 'Website' ) . '</label>' . '<input id="url" name="url" type="text" value="' . esc_attr( $commenter['comment_author_url'] ) . '" size="30" /></p>',
        ); 
    );
    comment_form($args);

You just have to comment the line of the Website, and pass the array like in the exemple.

Answer 2

you can try adding this filter to your theme's functions.php:

add_filter('comment_form_default_fields', 'remove_url');
function remove_url($val) {
    $val['url'] = '';
    return $val;    
}
