Forum friends might be friends with the admin too. Nobody may want to get involved in a personal conflict between two people. You can make another account, but I think the new admin will figure you out sooner or later and block you. You should somehow sort things out with him, and then communicate normally. For now you can access the forum through free web proxy site online https://gologin.com/free-web-proxy/ . It will let you avoid downloading or installing anything. You just use this link in your browser, it already has a built-in proxy that substitutes your IP.
