Google's safe browsing API is probabilistic too. The idea is that you do so many rounds of checking to get closer and closer to the mark. You start with a fairly high false positive probability, high-privacy check, then if you get a positive, you try a lower false positive rate check that also loses you some privacy, and the trade-off is that you don't have to have the full malicious site DB with you at all times (and keep it up to date). Why did you assume I'd not know about false positives?
