> Is using puppeteer to automate a form submission a violation of ToS? If so then why is using a screen reader not?

Without taking a position on the ethics of automation, surely this isn't a serious question? Things that the ToS prohibits you from doing are ToS violations, and other things aren't.

For instance, from AirBnb's terms of service: "Do not use bots, crawlers, scrapers, or other automated means to access or collect data or other content from or otherwise interact with the Airbnb Platform."

There is no similar prohibition against using screen readers.

My broader point is that these ToS clauses are often so broad and vague that they're essentially unenforceable and not meaningful in practice. For example, "Do not use bots" covers a pretty substantial amount of ground, and intention isn't exactly something you can screen for. Is an autofill chrome extension a bot? If so what separates that autofill from accessibility extensions? Is someone using Whispr flow to fill forms considered a bot? AirBNB doesn't block Google's crawler. Why? A company can enforce its TOS as it wishes. My general point is that the waters are murky, and that automation is a sort of sliding scale.

Under that ToS would a screen reader not be considered “other automated means” of “interacting with” the platform? It is automatically walking an accessibility tree.

A screen reader uses automated means to access or collect data or other content from or otherwise interact with a platform.
