For April Fools Day 2022, Off on a Tangent became a “robots only” website that required you to fail a “CAPTCHA” test before viewing the site. You can see the prompt and how it worked by clicking here. Here’s the message that appeared on the site:
For security reasons, Off on a Tangent is now a “robots only” website. Human use of the site is prohibited. I’m sorry that it has come to this.
Visitors attempting to access the website will now be given a security prompt and will have to disprove their humanity by failing at least two “CAPTCHA” tests before being granted access.
I, for one, welcome our new robot overlords.
