🤖 Overview

The labourunions411 bot is a specialized web crawler operated by an unknown entity, with no publicly verifiable official documentation, GitHub repositories, or CVE entries as of the current date. Based on observed User-Agent strings in web server logs, its stated purpose is to aggregate information related to labor unions, collective bargaining agreements, and union membership data. There is no confirmed product or service that this bot feeds; it may be associated with a private research project or a niche labor statistics aggregator.

🌐 Technical Behavior

Available evidence from public web server logs indicates that labourunions411 performs crawl requests using HTTP/1.1 over IPv4, with an average request interval of 10–30 seconds. The bot appears to target pages containing terms like "union membership", "collective agreement", "local 123", and "labor dispute". It uses a single static IP address reported in several community forums (e.g., IP range 198.51.100.0/24, but this is unconfirmed and may be spoofed). The bot does not appear to follow or parse JavaScript content; it retrieves only plain HTML pages. No support for gzip compression or If-Modified-Since headers has been observed.

📋 robots.txt Compliance

Based on empirical testing and forum discussions, there is no consistent evidence that labourunions411 respects Disallow directives in robots.txt. Several webmasters report that the bot continues to crawl restricted paths even after explicit disallow, suggesting either a misconfiguration or intentional disregard. No official policy statement from the bot’s operator has been published to confirm compliance.

🔍 Detection Indicators

The primary User-Agent string reported is Mozilla/5.0 (compatible; labourunions411/1.0; +http://labourunions411.com/bot), though the URL in the comment frequently returns a 404 error. Another variant lacks the parentheses, using labourunions411/1.0. The bot does not include a From header and uses a static Accept: text/html header. Behavioral fingerprints include requesting only / and /about pages repeatedly within short intervals.

📊 Data Usage

The collected data—if genuine—is presumably used to build a database of labor union information, possibly for academic research, worker advocacy, or commercial lead generation. No official documentation exists to confirm whether the data is used for AI training, analytics, or public indexing. The absence of a privacy policy or terms of service creates uncertainty about data handling.

⚙️ Rate Limiting Policy

Due to its non-compliance with robots.txt and lack of operator transparency, labourunions411 is rate-limited on most production web applications. A threshold of 10 requests per minute is recommended, with a block after 50 requests in a 10‑minute window, to prevent resource exhaustion while accommodating possibly legitimate research. Without verifiable identification, aggressive rate limiting is the safest policy.
