To avoid this in the future, just added this to my Caddyfile:

    @aibots {
        header User-Agent *GPTBot*
        header User-Agent *ChatGPT*
        header User-Agent *anthropic-ai*
        header User-Agent *ClaudeBot*
        header User-Agent *OAI-SearchBot*
        header User-Agent *Google-Extended*
        header User-Agent *FacebookBot*
        header User-Agent *CCBot*
    }
    abort @aibots

Reusable 100%.
