Obviously, you guys never used Tor. When you try to search anything in Google while using TorBrowser, not only will you be hit with CAPTCHA almost every time, Google will also sometimes refuse to show you CAPTCHA, or will show it, but refuse to let you use audio CAPTCHA. And even if it let’s you do the test, it will claim multiple times that your performance is inadequate and force you to repeat the test. Then, when you pass, it will sometimes hit you with CAPTCHA again. Why? Hell if I know.
This got so bad that I almost never use Google with Tor these days, making do with DuckDuckGo.
