I don't see how captchas are "fundamentally cracked" if they only claim a success rate at best around 2/3rds. Nor do they give an explanation for what they mean

- sobellian 9y agoA captcha is cracked if it becomes economical to try to pass it over and over again. If you have a script that succeeds in spamming a forum 2/3 times it tries, you've got a successful spamming system. What they mean by fundamentally cracked is that this method seems to be more robust against minor variations of spacing, font, etc. than CNN-based models.
- ComputerGuru 9y agoBefore you can say that a 66% success rate isn't good enough, you need to compare it to the human success rate. I barely get 2/3 myself.

- a_imho 9y agoThis is my experience as well, very frustrating being locked out of your account when you need to take care of business. Nevermind cracked, they are fundamentally broken if a human can't get a nearly perfect success rate.
- willchang 9y agoCaptchas are useless for their intended purpose if a bot can get it right better than every other time.
