It's definitely not a human. It's most likely a headless browser like Selenium or Puppeteer. There was an old 4chan spammer, DelayClose,  which handled proxies, a folder of randomized images and whatnot, which works similarly.

But there are python scripts out there too, on github that do similar things, probably with OCR integration. Tho non-text/interactive captchas need more.
I know Puppeteer has a plugin where you can integrate captcha solver services such as 2captcha, I assume other headless browsers have the option.

No, we fixed that. Plus we have stats from recaptcha.
