AFAIK, Anubis does not work alone, it works together with traditional per-IP-address rate limiting; its cookies are bound to the requesting IP address. If the scraper uses a new IP address for each request, it cannot reuse the cookies; if it uses the same IP address to be able to reuse the cookies, it will be restricted by the rate limiting.
