Dear Rabbi
Dear Rabbi Zahavy,
I am on Facebook a lot and have many friends there. Recently, one of those people, whom I have known for many years, started replying negatively on every post that I made and on every comment that I put on Facebook. These were not just critical replies. They were snarky at first, and then became nasty and highly personal in nature.
I unfriended this person. But somehow, he still manages to find and comment on all my posts. What should I do to stop this?
