Is this some sort of scam? A local paper has published a big article claiming that thousands of people in my area have been found to have their information on a list which criminals are selling on the dark web, talking about identity theft. The end of the article gives this url.
I had a look. You put in your email address, they send you a mail with a verification link, and when you've verified you get another email showing what data they have discovered on this list which is being touted on the dark web.
There are also links to a page on their site which will sell you software to protect you from further thefts or alert you to further thefts etc.
The email also tells you to delete it after you've viewed the information 
Once I saw they just wanted to sell me software I kind of dismissed it all. There is some info on me, but it's only name and address which is public record anyway, and I believe the Electoral Roll is being sold these days.
What did interest me was their instruction to delete the email. Why on earth would you have to do that? Are they trying to make it all a bit Mission Impossible? Why isn't their email self-destructing?
