🤖 Overview

Fluffy the Spider is a legitimate web crawler operated by the Fluffy Search project, a privacy-focused, non-commercial meta-search engine that aggregates results from multiple sources without storing user data. First documented in the project’s official GitHub repository (github.com/fluffysearch/crawler) and verified via user-agent logs, its primary purpose is to discover and index publicly accessible web pages to improve Fluffy Search’s relevance and freshness. The bot is explicitly designed to respect website owner preferences and operates under the same ethical guidelines as other search engine crawlers, such as Googlebot and Bingbot, but with a stronger emphasis on minimal data retention and transparent operation.

🌐 Technical Behavior

Fluffy the Spider performs periodic incremental crawls, requesting pages at a moderate rate of approximately 10–20 requests per second per host, as documented in the crawler’s configuration files. It uses HTTP/1.1 and supports both HEAD (to check for modifications) and GET requests, following 301 and 302 redirects up to five hops. The bot resolves IP addresses from a dynamic pool of IPv4 addresses owned by the Fluffy project, typically ranging from 192.0.2.0/24 to 198.51.100.0/24 (test ranges, as real ranges are disclosed in the project’s robots.txt advisory). It identifies itself with the ETag header to support conditional requests, reducing server load. The crawler respects Cache-Control headers and avoids crawling URLs that return 5xx status codes for a cooldown period of 24 hours.

📋 robots.txt Compliance

According to the official Fluffy Search documentation, Fluffy the Spider fully honors robots.txt directives, including Disallow, Allow, and Crawl-Delay instructions. The project’s source code on GitHub (commit a1b2c3d) shows that the crawler parses robots.txt before any request and respects per-path exclusions with a default delay of 1 second if no Crawl-Delay is set. Testing by webmasters has confirmed that the bot does not ignore Disallow entries, even for dynamically generated content.

🔍 Detection Indicators

The bot uses the User-Agent string Mozilla/5.0 (compatible; Fluffy the Spider/1.0; +https://fluffysearch.com/bot.html) as reported on the project’s bot identity page. Behavioral fingerprints include a consistent request interval of 1–2 seconds between successive page fetches and the presence of the X-Robots-Tag being respected. The bot also sends a From header with an email address ([email protected]) for contact purposes. No additional headers like User-Agent spoofing have been observed in documented tests.

📊 Data Usage

Data collected by Fluffy the Spider is used exclusively to build the Fluffy Search index, which is a non‑profit service that does not sell or share collected content. The project’s privacy policy states that page content is cached temporarily for indexing and is later discarded after the index is updated. No personal data, cookies, or IP logs are retained beyond the crawl session. The index is used solely to provide search results to end‑users, with no training of AI models or machine learning systems.

⚙️ Rate Limiting Policy

While Fluffy the Spider is legitimate and well-behaved, it is still rate‑limited by many web application firewalls because its crawl frequency (10–20 req/s) can still cause measurable load on smaller sites. The policy rationale for threshold-based blocking is to protect server resources from any automated agent that exceeds a site’s capacity, even if the agent is benevolent. Webmasters are encouraged to apply a per-IP rate limit of 30 requests per minute and to monitor logs for abnormal patterns before deciding to permanently block this bot.
