This shouldn’t be necessary. We changed our handling of Tor so long ago that I’ve forgotten how long go it was. If you are using the Tor Browser Bundle you should not see a CAPTCHA. If you do please report it to us.
I'm seeing the CAPTCHA a lot with the Brave Browser Tor Tab. You might want to reach out to the developers to make their Tor Tab be treated the same as the Tor Browser Bundle.
OK. I don't like that. I messaged the team about this.
