The REAL answer is, let's say Joe Schmuckatelly not knowing any better clicks on an email like you are discussing. It takes him to what APPEARS to be a cox login page. and he logs in, username and password. What's he's done is get phished, and now they have HIS email name and pwd. So when they can no longer send out phishing or scam emails using the susieq@cox.xxx, NOW they start sending emails out using the jschmuckatelly@cox.xxx, a few of them of course are phishing emails to get more usernames and passwords and the rest are scam emails for banks/credit cards etc etc. That way one or more of the phishing emails gets them some more usernames and passwords, while the rest are used to get into banks, cc's, etc etc to steal money.
BTW, I am a Senior Citizen, BUT know better, having worked as a systems engineer, network engineer, when discharged from the navy was working AIS Security, so I am one of the Senior Citizens who know better. I do my best to spread the knowledge, and assist everyone I can in alerting them how this happens. I also take scammer calls, and use a virtual machine to waste their time, HOURS of it if possible, as a way to entertain myself, and ensure that while I am wasting their time, they are not stealing money from someone else. (It's best to use Windows Vista 32 bit, since there are only a couple of remote software packages that will run on it, so they waste a LONG time going through every single one of them, till one finally loads up, LOL LOL).
