The false positive rate is the proportion of sites tagged as fraudulent that shouldn't be. Not the proportion of all registrations. So it will be fewer than 250 falsely tagged sites. The paper does not seem (on a quick scan through) to suggest what proportion of registrations are fraudulent, but that 0.35% should be applied to that number not the total number of registrations.
