Quick note: the term used in conversation was "k-privacy", but what was really meant way "k-anonymity". There is a conceptual overlap with "differential privacy". Naturally, it is easy to mix up the wording.
Not being able to update the wording on Steemit is limiting. It is perhaps one place where non-immutable is frustrating. =)
