Blocking Google AI (Bard and Vertex AI generative APIs)

Add the following two lines to your robots.txt:

User-agent: Google-Extended
Disallow: /

For more information, here’s a list of the user agents used by Google crawlers and fetchers. However, Google does not provide CIDR, IP address ranges, or autonomous system information (ASN) to block its AI bot that you can use with your web server firewall.

Blocking commoncrawl (CCBot) using the robots.txt file

Add the following two lines to your robots.txt:

User-agent: CCBot
Disallow: /

Although Common Crawl is a non-profit foundation, everyone uses data to train their AI by its bot called CCbot. It is essential to block them, too. However, just like Google, they do not provide CIDR, IP address ranges, or autonomous system information (ASN) to block its AI bot that you can use with your web server firewall.

Blocking Perplexity AI using the robots.txt file

Another service that takes all your content and rewrite it using generative AI. You can block it as follows:

User-agent: PerplexityBot
Disallow: /

They also published IP address rages that you can block using your WAF or web server firewall.

Can AI bots ignore my robots.txt file?

Well-established companies such as Google and OpenAI typically adhere to robots.txt protocols. But some poorly designed AI bots will ignore your robots.txt.

Is it possible to block AI bots using AWS or Cloudflare WAF technology?

Cloudflare recently announced that they have introduced a new firewall rule that can block AI bots. However, search engines and other bots can still use your website/blog via its WAF rules. It is crucial to remember that WAF products require a thorough understanding of how bots function and must be implemented carefully. Otherwise, it could result in the blocking of other users as well. Here is how to block AI bots using Cloudflare WAF:

Please note that I’m evaluating the Cloudflare solution, but my primary testing shows it blocked at least 3.31% of users. The 3.31% is the CSR (Challenge Solve Rate) rate, i.e., humans who solved the captcha provided by Cloudflare. That is a high CSR rate. I need to do more testing. I will update this blog post when I start using Cloudflare.

Can I block access to my code and documents hosted on GitHub and other cloud-hosting sites?

No. I don’t know if that is possible.

I am concerned about using GitHub, a Microsoft product, and the largest investor in OpenAI. They may use your data to train AI through their ToS updates and other loopholes. It would be best if your company or you hosted the git server independently to prevent your data and code from being used for training. Big companies like Apple and others prohibit the internal use of ChatGPT and similar products because they fear it may lead to code and sensitive data leakage.

Is it ethical to block AI bots for training data when AI is being used for the betterment of humanity?

I have doubts about using OpenAI, Google Bard, Microsoft Bing, or any other AI for the benefit of humanity. It seems like a mere money-making scheme, while generative AI replaces white-collar jobs. However, if you have any information about how my data can be utilized to cure cancer (or similar stuff), please feel free to share it in the comments section.
