All good advice here Sooz, I posted about these types of emails a while back. I was receiving 3-6 of them a day in each of my vermontel.net addys. Although I'm not a current customer, CapitalOne keeps sending me credit alerts, and yesterday I found at least 8 instances where one of my vermontel addys is on the Dark Web, and that the password had been exposed. And sure enough, one of my old, much simpler passwords has come through several times in these extortion emails. I've been working with the techs at VTel internet and changed my passwords (again), and one thing that has helped immensely to keep these emails out of my inboxes was to lower the "score" threshold of their Spam Filter, Roaring Penguin. This has kept 99% of these annoying emails out of my inbox. Eventually, as time permits, I will probably need to dump these accounts, but am keeping them for now because there are folks out there who just don't want to change my contact info for whatever reason. Keeping different and complex passwords over different sites will also help greatly. And depending on your ISP, they may be able to adjust the threshold of what comes into your inbox as well. I was spending an inordinate chunk of time every day scrolling through what was mostly junk in the email quarantine, and now it just takes a few seconds to go through the quarantined messages to ferret out any legitimate messages.
And the admins work really hard here to keep these jerks out of our Forum!
HTH,
Chris
