Recently, I typed the name of a known website into my phone, but unbeknownst to me, one digit was not captured. I ended up at a fake website where someone tried to con me into believing a free service now costs money. Luckily, I caught on, but I might easily not have done so. Because I typed the address myself, I did not check it until later on. That website has been removed, perhaps because I wrote to the FCC and any other agency I thought might act on it, but surely there are many, many more. I suspect people, no matter how savvy, are less cautious when they initiate contact.
