Can't hide the stars from Github itself though. Keeping as much preference data away from social networks as possible is not an unreasonable stance, IMHO.

You also can't hide the fact that you're browsed or even cloned the repository from GitHub, since it's on their servers.

not a bad idea. in that case you can just bookmark them, no?
