Seeing as Tyki probably doesn't know squat about electronics, and doesn't really private anything- what he does private, she could probably hack. (Unless it's super important to plotting or something but that's not likely. I'll note it if it is, or something.) What he replies into is up to the poster who initiates it though, as I bet Earl's a lot better at his privacy settings.
One day Kitty, you must confound him with knowledge of the modern times.
