You don't need a human for captcha. You can put together software pretty easily now that'll solve some captchas some of the time, and with automation even a 5% success rate means you can still get thousands of accounts.

- tedivm 9y agoThe captcha tends to be during signup, not just any general request. Otherwise third party clients wouldn't work at all. So there isn't any "account" with 95% failure, only IP addresses that fit that. However, spreading requests to multiple IP addresses can help get around that, and botnet rental is pretty cheap these days (cheaper than the captcha prices that have been quoted).

So that third party clients wouldn't work is a given. And since they wouldn't work, there's no reason why Twitter couldn't show a captcha many more times after signup.
