123stitch.com and csudh.edu

123stitch.com #51,770 csudh.edu #51,768

Measured takeaway

123stitch.com blocks AI-search crawlers; csudh.edu allows AI-search crawlers.

csudh.edu's robots.txt disallows every crawler; 123stitch.com's does not.

Measured in Botfy's 2026-09-07 publication.

At a glance

A difference appears only when both sites have comparable evidence. Unavailable or unresolved observations remain incomplete.

Evidence123stitch.com csudh.edu
robots.txt Served and parsed Served and parsed
Google crawl posture Open Blocked
Unnamed crawler fallback Partly Restricted they inherit the wildcard (*) group's rules Blocked the wildcard (*) group disallows everything, so they are blocked without being named
Base /llms.txt Not probed Not found when probed

Treatment by purpose

Only resolved blocked, allowed, or mixed states count as a policy agreement or difference. Unnamed agents still inherit each site's wildcard rules.

Model training Blocked Not explicitly addressed
AI search Blocked Allowed
Live assistant fetch Blocked Not explicitly addressed
Opt-out directives Not explicitly addressed Not explicitly addressed
Ambiguous / undocumented Not explicitly addressed Not explicitly addressed

Named agents

Measured differences appear first. “Not explicitly addressed” is not the same as allowed; the site's wildcard fallback governs that crawler.

How each site compares with its own rank peers

The sites may belong to different rank bands. Each percentage keeps its own population and denominator; Botfy does not subtract rates from unlike cohorts.

How this comparison is measured

Both sites use Botfy's latest published observations. A missing fetch, unresolved agent verdict, and measured absence are different states. Peer percentages use each site's exclusive Tranco rank band and print their own denominator. Populations, sources, and limits →

Keep comparing

Each suggestion replaces one side using an editorial collection or current rank proximity. Neither means the sites have similar policies.
