Web puzzles don't protect against bots, but humans have spent 819 million unpaid hours solving them
I don't know, it is clear that Google is getting free labor out of users solving their captchas.
However, I disagree with captchas being ineffective. If captchas were so ineffective there won't be sites dedicated to having people in developing countries solve them.
It is very easy to make a script that makes accounts by sending post requests without captchas. It requires little skill. You can see this with new lemmy instances being filled with spam until the admin adds a captcha or questionnaire.
They are absolutely effective. Effective at getting me to just press the back arrow and find an alternative website that doesn't disrespect my time.
For a robot, that was a highly opinionated statement. Crazy what technology can do these days
