Blocking and ghosting are not new, not something only the current generation invented. Only the terminology is new. I used to have fun using selective redirection when I wished to avoid someone. I would have their call automatically redirect to their own number so that whenever they called they would get a busy signal. For some reason you can’t do that on modern “smart” phones, tho’ you could do it on old BlackBerrys. New iPhones will block, but not divert. Ghosting has always been around — there are songs, many of them, dating as far back as the ’50s about heartbroken people waiting by phones for calls that don’t come.
