I unfollowed this group, tried blocking, etc but he is still doing this. I have told him to leave me alone but he is still showing up in my notifications. I am starting to get very concerned with this behaviour. Should I contact the police. It’s a group against mistreating animals, but they hate humans and not only say it but are so nasty to others. They seem to be really sick people. What can I do? I did report it to FB, but no reply.
