People could send hatemail and death threats in the mail before landlines existed. Sure, technology makes it easier to send anyone anything but progress has been made to make certain things more private. You can block someone on facebook or heavily lock your profile down to be invisible anyone but friends. You can block numbers easily on phones now. Encrypt your phone or computer (by default now!) to prevent people from installing tracking apps or spyware. You can use things like whatsapp to talk without the cell carrier recording phone numbers. GPS trackers are still an issue, I can't think of any way to get around that other than using a GPS jammer which is illegal and wouldn't block a tracker that uses cell towers as well. Cell phones and pagers used to be just as dumb as a landline, they receive everything and track everything but you can stay much more "off the grid" while still remaining in contact now.
