If you have access to your site's code, there's an easy way to tell AI bot scrapers you don't want your website content to be used. Note they can choose to ignore this, but most will follow it.
If you have your domain on Cloudflare, you can use their AI bot protection! There are two sections to update:
Security
Click on your domain name in Cloudflare.
Go to Security → Bots.
Turn on "Block AI Bots" and "AI Labyrinth".
AI Audit
Click on your domain name in Cloudflare.
Go to AI Audit.
Set AI items to Block. Note you will still want to enable Googlebot and BingBot so your site can appear in search engines. I also recommend leaving archive.org_bot allowed.
