Well I'd still strongly suggest you apply since ABP whitelists a wide variety of websites, I believe the relevant personnel can guide you to something agreeable to both parties.
Worst that could happen is that the website won't be whitelisted which it still isn't so it won't harm you... On the contrary, if things works out, it will definitely help. 60+ million users is not a small number by any means in my humble opinion.
Rest is up to you. I'm just trying to help
