Additional checkboxes in the comment fields

What would those checkboxes do? Save data to the database? What kind of data?

No, no, no, no. Not so complex. The point is: I have a lot of comments and most of them don't read the FAQ page. So before anyone can post a comment, they have to check the box that they have read the FAQ page.

Something like this: http://prntscr.com/l0fjnm

Maybe this will work?:

add_action( 'comment_form_after_fields', function() {
    ?>
        <input type="checkbox" value="" /> Some text here
    <?php
} );

Thanks

No problem :)
