He blocked her?

A guy that has talked to my friend he is one of her ex flings friends. So they did talk for 3 weeks or so but it went a bit downhill when she mentioned her ex fling which is his friend. Anyways thats the background story of this main question. She posted a photo of this guys pet cat on her instagram story and wrote something cute about it and wanting to have one. He then after seeing it wrote why would she post that and blocked her. This is so funny to me is there more to it?
