How could anyone find out which sites are you following using an RSS feed? And I mean in a broad way: can the site track you? Can ISP? Network managers?

Let’s say you want to follow a bunch of political sites that you don’t want to be easily attached to, is RSS a good way to do it? Are there extra precautions to take?

My first thought would be that it’s the same as using any other browser, so not a great way to be private. Am I wrong?
