Comment:

 It's a pretty clever way to spam. The `esc_html` of course helps with XSS,
 but the text itself is part of the page.

 Suggesting a patch with `add_filter( 'wp_robots', 'wp_robots_no_robots'
 );` when the search query is fetched. I think it wouldn't be possible to
 track all use cases unless we grep-and-fix `$_REQUEST['s']` for user-
 search related pages, but I hope the patch is a start.
