This is an old trick. For example all MailChimp embed forms have dummy inputs that are visually hidden but might be filled in by bots.

- sph 3y agoMaybe not visually hidden, but practically invisible to human: imagine a text box with color #fffffe on a white background. Visually impossible to discern for most humans on most screens, but for a machine #fffffe is totally distinct from #ffffff, and fully visible if display != none. As AI becomes more intelligent, you can prove humanity by exploiting our weaknesses. (Another idea. Have a random image on a page actually be a text box with an image background. You cannot activate it if you focus on it, with your mouse or touch, but a bot doesn't need focus to change input.value.)
- cletusw 3y agoPlease don't do this. This confuses and possibly prevents screen reader users from using your site.
- yjftsjthsd-h 3y agoOne pitfall: Screen readers will happily get caught on that. Of course, a11y concerns and bots tend to look similar in general, which is a perennial sticking point.
