Linux 7.1

You have encountered this screen because the site administrator has implemented Anubis, a defensive measure designed to shield the server from the aggressive data-harvesting practices of AI corporations.

The Problem

When AI companies scrape websites at scale, it often leads to significant server instability. This results in:

• Increased Latency
• Unexpected Downtime
• Unrestricted Access $\rightarrow$ Total Inaccessibility for all legitimate visitors.

How it Works: Proof-of-Work (PoW)

Anubis utilizes a computational challenge known as a Proof-of-Work system. This approach is modeled after Hashcash, which was originally designed to mitigate the volume of email spam.

The mathematical logic follows a basic principle: $\text{Cost}_{\text{total}} = \sum_{i=1}^{n} \text{Work}_i$

Where $n$ is the number of requests. For a single human, the cost is trivial; for a mass scraper, the cost becomes astronomical.

User Category	Resource Impact	Experience
Individual Human	Negligible	Seamless access
AI Scraper	Cumulative/Heavy	Prohibitively expensive

The Long-Term Strategy

This PoW page is merely a temporary stopgap. The ultimate goal is to refine browser fingerprinting techniques to better distinguish humans from headless browsers. For example, by analyzing how a client handles font rendering, the system can bypass the challenge for likely humans.

Technical Requirements

To successfully pass the Anubis gateway, your browser must support modern JavaScript. Certain security extensions—specifically JShelter—will block the necessary functions.

To regain access, please complete the following:

• Enable JavaScript in your browser settings.
• Disable JShelter or similar restrictive plugins for this specific domain.

// Conceptual PoW Verification
if (client.solveChallenge(nonce) === targetHash) {
    allowAccess();
} else {
    denyAccess();
}

"Unfortunately, the necessity of this barrier arises because AI companies have fundamentally violated the social contract regarding the nature of website hosting."
