Can an AI agent sign up for Mastodon (mastodon.online)?

Email form, no CAPTCHA seen before submit checked 2026-10-09

Probably yes. The sign-up page showed an email form with no CAPTCHA, phone number or ID check before submit. A live signup would confirm it.

What the front door showed

Sign-up page: https://mastodon.online/auth/sign_up (HTTP 200, title: Log in - Mastodon.online).

• email field: yes; password field: yes; phone field: no
• visible CAPTCHA: no; invisible CAPTCHA script: no; bot wall: no

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.
