Please read http://www.blackhatworld.com/blackhat-seo/black-hat-seo/552133-my-competitor-ranking-no-1-no-backlinks-how.html#post5420889. Blocking ahrefs IP's won't block the crawlers from accessing the backlink pages.

Please read post #13. Blocking ahrefs IP's won't block the crawlers from accessing the backlink pages.

Here blocking the Ahref refers to the site from which he is getting backlink. Like we might be running a private blog network with ahrefs blocked.
