The headline "Facebook's ad filtering is so good it only lets 0.0000001% bad add through" doesn't sounds like good click bait to me, despite it being an impressive achievement if true. So here we are.
Facebook has about 3 billion daily users. I expect each will see many ads - probably 10 or more. But if we assume it's just one, 100 displayed in a single day would give you 0.0000001%. The study didn't look at one day of course - the observation period was over 100 days.
