What this challenge teaches

Teaches: Substring match against known scraper UAs. Easy to defeat, but easy to forget.

Expected output: Set a browser-shaped User-Agent (Mozilla/5.0 ...) and you pass.

Submit your scraper's JSON output to /challenges/antibot/ua-blocklist/grade (grader endpoint is part of a later phase; URL is reserved now).

Passed. Your UA doesn't match the blocklist.

Your UA: Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com)
