@dredmorbius I'm not sure if we're discussing the same thing here. People who publish stuff publicly will always be targeted, they have a certain set of precautions to take. They're not what I'm talking about.
The news article you linked was related to (identifiable) _subscribers_ to this information. They _would_ be safe simply by using Tor and anonymous RSS/Atom feed subscriptions. ('xcept maybe some timing attacks, but they're easily muffled with having some more traffic than just this feed).
But as I said, I think I have strayed from the subject. The point I wanted to get across was that anonymous subscriptions are totally possible in !OStatus, assuming the data transfer can be trusted.
