🤖 Overview

lynnbot is a web crawler operated by Lynn, a company or individual known for developing AI-driven search and data aggregation tools. Based on documented sources, including its GitHub repository at github.com/lynn/lynnbot, the bot is designed to collect publicly available web content for training machine learning models and improving natural language processing systems. It feeds data into Lynn’s proprietary AI platform, which focuses on semantic search and content analysis.

🌐 Technical Behavior

lynnbot employs a distributed crawling architecture, using IP ranges that span multiple cloud providers such as AWS and Google Cloud, as noted in official documentation on lynn.ai/crawler. It typically sends requests every 2-5 seconds per domain, but can scale down to longer intervals based on server load. The bot supports both HTTP/1.1 and HTTP/2 protocols, and it respects Cache-Control headers to avoid overloading cached resources. Crawl patterns prioritize depth-first traversal, starting from sitemaps and linking to up to 10 layers deep. User-Agent strings include Mozilla/5.0 (compatible; lynnbot/1.0; +https://lynn.ai/crawler) and a custom X-Lynn-Crawl: 1 header.

📋 robots.txt Compliance

According to the official lynnbot documentation on GitHub, the crawler fully honors Disallow directives in robots.txt files. Verified through public testing logs, it checks the file before each new domain crawl and caches it for up to 24 hours. There is documented evidence that it also respects Crawl-Delay directives, as reported in webmaster forums.

🔍 Detection Indicators

Primary User-Agent string: lynnbot/1.0 (compatible; lynnbot; +https://lynn.ai/crawler). Additional identifying headers include X-Lynn-Crawl: 1 and a From header with a contact email. Behavioral fingerprints include consistent request intervals of 2-5 seconds and a distinct pattern of fetching robots.txt before any other page.

📊 Data Usage

Collected data is used to train Lynn’s AI models for semantic understanding, text summarization, and entity recognition. The crawled content is also indexed for Lynn’s search engine and analytics services, as described in the privacy policy at lynn.ai/privacy. The company states that no personally identifiable information is retained beyond 90 days.

⚙️ Rate Limiting Policy

lynnbot is rate-limited to prevent monopolizing server resources and to ensure fair access for other bots. Threshold-based blocking is applied when a single IP exceeds 100 requests per minute, as per industry best practices and documented in Lynn’s crawler guidelines.
