Captchas are well known for keeping automated spammers out and letting humans in. However, ReCaptcha is a rather clever service using them to help
I recall reading a story a while back about someone providing "captcha answers as a service", and rather than being AI, it was... well, they had a porn site, and when they got a request in for "solve this captcha for us", they'd present it to the next "customer" visiting their porn site as some sort of deal "solve this captcha to prove that you're human in order to get (some amount) of free time on our website" - and their "customer" who thought they were getting a great deal were actually solving a captcha that was allowing a bot to, say, sign up for a social media account somewhere. Ingenious, if not particularly ethical. And it would require a fairly constant stream of incoming customers, in order to be able to supply real time responses.
