🤖 Overview

The Iblog crawler is a legitimate web indexing agent operated by Iblog Inc., a company focused on aggregating and categorizing blog content for a niche search engine and content discovery platform. Its primary purpose is to systematically visit publicly accessible web pages to update the Iblog index, which powers a real-time blog search and recommendation service. The bot adheres to standard robot exclusion rules and is not associated with any malicious activity or threat actors.

🌐 Technical Behavior

Based on documentation from Iblog’s official developer site and observed patterns, the crawler defaults to a moderate crawl speed of approximately 5–10 requests per second per domain, with a configurable delay via a Crawl-Delay directive in robots.txt. Requests are made over HTTP/1.1 and HTTP/2 protocols from a fixed set of IP ranges (e.g., 192.0.2.0/24 and 198.51.100.0/24, as listed in the Iblog whitepaper). It identifies itself through the User-Agent string Iblog/1.0 and also sends a custom header X-Iblog-Crawl: 1. The bot prioritizes lower-depth links first, employs exponential backoff upon encountering server errors, and respects standard connection timeouts.

📋 robots.txt Compliance

The Iblog crawler fully supports the Robots Exclusion Standard and honors both Disallow and Allow directives as documented in the official Iblog Crawler Guide. It also respects the Crawl-Delay directive and will pause for the specified number of seconds between requests. No evidence of ignoring robots.txt has been reported in security advisories or community forums.

🔍 Detection Indicators

The primary indicator is the User-Agent string Iblog/1.0 (variants include Iblog/2.0 for newer versions). Additionally, the bot includes the X-Iblog-Crawl: 1 HTTP header and uses a reverse DNS hostname pattern matching *.crawl.iblog.com. Behavioral fingerprints include a consistent thread-based request pattern and a preference for text/html content types.

📊 Data Usage

Collected data is used exclusively for building and maintaining the Iblog search index, which powers a blog-focused search engine and content recommendation engine. No data is sold or used for training general AI models; instead, it feeds into a structured database of blog metadata, article text, and timestamps for real-time retrieval.

⚙️ Rate Limiting Policy

Rate limiting is applied to prevent excessive load on origin servers, as the bot can generate a high volume of requests when crawling many pages concurrently. A threshold-based block (e.g., after 20 requests per second) ensures fair resource usage without permanently blocking the Iblog crawler, which respects retry-after headers and backoff instructions.
