+## Personal and Sensitive Information
+
+This dataset is a heavily filtered version of the Common Crawl dataset. CommonCrawl respects robots.txt and will not include websites if their robots.txt say so. Even so, if you find that your website was included you can submit a [removal request](https://docs.google.com/forms/d/e/1FAIpQLSddAIuUui5xnAzBqft6MnzPYihr-AaS-Nj8x01Y6AM8NQ0YLQ/viewform?usp=sharing) indicating that you are the owner of the website.
+
+In this dataset, measures are taken to anonymise email addresses and public IP addresses following the [FineWeb-2 approach](https://huggingface.co/datasets/HuggingFaceFW/fineweb-2#personal-and-sensitive-information-and-opt-out). Email addresses matching a regular expression are replaced with `firstname.lastname@example.org`. Similarly, IP addresses allocated for [public networks](https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-special-registry.xhtml) are replaced by unused IP addresses. Despite these best efforts on such large volumes of text, you may still encounter that your personal information is present in the dataset. In that case you can submit a [removal request](https://docs.google.com/forms/d/e/1FAIpQLSddAIuUui5xnAzBqft6MnzPYihr-AaS-Nj8x01Y6AM8NQ0YLQ/viewform?usp=sharing).
