🌈 Abstract

The article discusses Cloudflare's new feature to block AI bots from scraping website content without permission, in order to help preserve a safe internet for content creators.

🙋 Q&A

[01] Cloudflare's New Bot Blocking Feature

1. What is Cloudflare's new feature to block AI bots?

• Cloudflare has added a new "one-click" feature to block all AI bots from visiting websites, in response to customer demand to prevent AI bots from scraping website content without permission.
• This is in addition to the existing robots.txt file method, which Cloudflare says can be ignored by some bots.
• Cloudflare's machine learning-based bot detection system can identify bots even when they try to spoof their user agent to appear like a real browser.

2. Why is Cloudflare offering this feature?

• Cloudflare says this is to "help preserve a safe internet for content creators" and in response to customer "loathing of AI bots" that scrape website content without permission.
• There is a widespread belief that generative AI models are often based on "theft" of content, leading to lawsuits against AI companies.

3. How effective is Cloudflare's new bot blocking feature?

• Cloudflare claims 85% of its customers have already enabled the previous bot blocking feature.
• The new one-click feature aims to provide a more robust barrier against bots that may ignore the robots.txt file.
• However, Cloudflare acknowledges that some AI companies may persistently adapt to evade bot detection, and they will continue to evolve their machine learning models to address this.

[02] Limitations of Robots.txt for Bot Blocking

1. What are the limitations of the robots.txt file for blocking bots?

• The robots.txt file, which is a widely used method for websites to specify which bots can access their content, can be ignored by some bots without consequences.
• Recent reports suggest that some AI bots, like those used by Perplexity, have been observed scraping website content despite the robots.txt directives.

2. How does Cloudflare's approach differ from relying on robots.txt?

• Cloudflare uses a machine learning-based bot detection system that can identify bots even when they try to spoof their user agent to appear like a real browser.
• This approach relies on digital fingerprinting to detect bots based on their technical details, rather than just relying on the robots.txt file.
