That said, it uses akismet for spam control, which I'm not sure how trustworthy it is... But definitely better than nothing!
Happy or not, I'm not sure that too many people seem to appreciate the data leakage that happens through WordPress and their affiliated products (such as Akismet). Considering how much people comment negatively about Gooogle Analytics, I'm always surprised that WordPress & co manages to slip under the radar, constantly. From https://automattic.com/privacy-notice/ (the owners of Akismet):
> Site Comments: When a visitor leaves a comment on a Site, we collect that comment, and other information that the visitor provides along with the comment, such as the visitor’s name and email address.
> Technical Data from a Visitor’s Computer and Etcetera: We collect the information that web browsers, mobile devices, and servers typically make available about visitors to a Site, such as the IP address, browser type, unique device identifiers, language preference, referring site, the date and time of access, operating system, and mobile network information.
> We may determine the approximate location of a visitor’s device from the IP address. We collect and use this information to, for example, tally for our Users how many people visit their Sites from certain geographic regions. If you’d like, you can read more about our Site Stats feature for WordPress.com sites and Jetpack sites.
> Akismet Commenter Information: We collect information about visitors who comment on Sites that use our Akismet anti-spam service. The information we collect depends on how the User sets up Akismet for the Site, but typically includes the commenter’s IP address, user agent, referrer, and Site URL (along with other information directly provided by the commenter such as their name, username, email address…oh, and the comment itself, of course).
> A cookie is a string of information that a Site stores on a visitor’s computer, and that the visitor’s browser provides to the Site each time the visitor returns. Pixel tags (also called web beacons) are small blocks of code placed on Sites. Automattic uses cookies and other technologies like pixel tags to help identify and track visitors and Site usage, and to deliver targeted ads
> We also collect any other information that our Users provide to us about visitors to their Sites. For example, a User may upload a directory or other information about Site visitors and customers to the “backend” administrative platform for managing the Site.
How We Use Visitor Information
> We use information about Site visitors in order to provide our Services to our Users and their Sites. Our users may use our Services to, for example, create and manage their Site, sell products and services on their Site, flag and fight comments from spammers, and collect information through polls, quizzes and other surveys.
> We may also use and share information that has been aggregated or reasonably de-identified, so that the information could not reasonably be used to identify any individual. For instance, we may publish aggregate statistics about the use of our services.
Then there's Gravatar, which is another method of user tracking and I'm sure there's a slew of other ways.
