It would appear that AW probably can't be bothered trawling through ads, testing their authenticity. They are happy raking in the money from private galleries etc. Yes they do take 30% of any revenue earned, which is quite a large chunk and the reason that most genuine SPs use their private galleries to fund their advertising(phone number display). The verified scheme is/was a good idea but if you chose not to have your verified photo on the front of your profile it's pretty useless in any search(my verification photo is still available, it just isn't on the front of my profile).
They are a site who's interests are their own, but I guess that also comes from running such a wide-reaching business too.
