Facebook has shadow accounts, so even if you don't even have an account on Facebook, they know exactly who you are, where you live, what you browse on the web, who your friends are, what you buy and where you buy it from, what illnesses you've been looking up on WebMD, who your health insurance is with, and so much more.
Twitter and Reddit aren't even playing the same game, let alone in the same league.
- throwawaysea 6y ago> Facebook has shadow accounts This is typical for every company to the extent that they have the data to do it. Reddit for example, can personalize your feed without needing an account, because they are able to track your behavior based on IP address. Google does the same thing across all their properties, such as YouTube, and arguably their presence is more pervasive than Facebook's.
