- Detection Notes
- CCBot traffic is primarily detected by the `CCBot` user-agent pattern; related patterns include `Common Crawl crawler`; a representative HTTP user-agent is `CCBot/2.0 (https://commoncrawl.org/faq/)`. Compare source IPs, reverse DNS, request paths, and crawl cadence with Common Crawl infrastructure before trusting the traffic.

- Yes
- Spoofing Risk
- CCBot has medium spoofing risk because the user-agent can be copied, even when the bot has strong source or documentation support.
