sportsyou.com and usafacts.org

sportsyou.com #29,426 usafacts.org #29,428

Measured takeaway

sportsyou.com blocks model-training crawlers; usafacts.org has mixed rules for model-training crawlers.

sportsyou.com blocks GPTBot; usafacts.org partly 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 Partly Restricted they inherit the wildcard (*) group's rules Partly Restricted they inherit the wildcard (*) group's rules
Base /llms.txt Related file observed at /ai.txt; /llms.txt not established 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.

Ambiguous / undocumented Blocked 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.
