To be clear, advertising bot detection is different to website bot detection. The website bot detection is because they're worried about spambots filling comments or DDOS attacks. This is where you get the captchas. The advertiser bot detection is more for the case where the website owner is in on it and trying to boost their metrics to get more revenue from advertisers, and is more likely to be expressed via blank ad slots and demands for refunds from the website owner.
