Alas, there are always those who think there are sheep to be shorn and, all too often, they are right.
Mind you, the banks don't help matters. I recently tore into one of them for sending out marketing mails with a link to follow. I got a snotty email back from a marketing drone telling me that I didn't need to click on the link if I didn't want to. Unfortunately, he chose the wrong idiot to debate with. Having worked for that bank, I happen to know one of the security officers pretty well, so I sent the original message and the response to him. He assures me that the drone won't be sending ANY emails to the public in the near future.
