Can an AI agent sign up for OpenML?

Refused our default headless browser checked 2026-10-09

Unclear. Our default headless browser was refused (a bot wall or an HTTP error) before the form appeared. Another browser setup may be treated differently.

What the front door showed

Sign-up page: https://www.openml.org/auth/sign-up (HTTP 500, title: The URL you requested has been blocked).

• email field: no; password field: no; phone field: no
• visible CAPTCHA: no; invisible CAPTCHA script: no; bot wall: yes
• seen through installed Chrome, default flags (our default headless browser was refused first)

What its rules say

We could not reach a rules or terms page from the sign-up page. A mention is not a ban: read the quote.
