Observed: ChatGPT-User

Daily request counts and verified share for ChatGPT-User.

The ChatGPT-User observation record on Rattlesnakes By Mail counts every request that Rattlesnakes By Mail logged from ChatGPT-User, day by day. Each daily row states the request count, the share of requests whose identity matched the vendor's published IP ranges or reverse DNS, and the formats served. A row appears only after Rattlesnakes By Mail logged at least one request from ChatGPT-User. Raw per-request rows are never exported, and every IP address is hashed with SHA-256 salted by the date before storage.

An unverified request is a request whose source IP address was outside the vendor's published ranges and whose reverse DNS did not resolve to the vendor; an unverified request is not proof of spoofing.

No requests recorded from this entity yet today.
