Did I get blocked?

A few months ago, I noticed a new player building shops and stuff near where I live. We would fight often for control of a couple areas in between us, up until about 2 weeks ago, I don't see him on the map, but his city is still there, and the areas we would fight over were left unclaimed. Did he block me? At first I was annoyed he was taking over my home areas, but I would get a lot of exp when retaking it, and I thought he would appreciate that too.

If he did block me, why can I still see his shops?
