Which personal data we collect and why we collect them
Comments
When visitors write comments on the site, we collect the data that appears in the comment form, the visitor's IP address, and the user agent string (which identifies the browser) to help detect spam.
From your email address, an anonymized string can be created (also called hash) and handed over to the Gravatar service to check if you are using it. The Gravatar Service's privacy policy can be found here: https://automattic.com/privacy/. After your comment is shared, your profile picture is publicly visible in the context of your comment.
