Measured takeaway

fortinet.com has mixed rules for model-training crawlers; theregister.com blocks model-training crawlers.

fortinet.com partly blocks GPTBot; theregister.com blocks GPTBot.

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.

Unnamed crawler fallback Blocked the wildcard (*) group disallows everything, so they are blocked without being named Blocked the wildcard (*) group disallows everything, so they are blocked without being named

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 Mixed Blocked
AI search Mixed Mixed
Live assistant fetch Mixed Mixed
Opt-out directives Mixed Blocked
Ambiguous / undocumented Blocked Blocked

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 →

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