The links may appear to go to a legit JDate site, but I wouldn’t trust that.
Tell her to ignore the emails and mark them as spam (if she can) and don’t respond directly back since that will let the spammer know she is a living, breathing person.
If the evil doers can lead her to a fake website they can try to capture all kinds of information about her.
I have an idiot that uses my email address as his own all the time and has signed up for all these dating sites. Apparently, he never realizes he never gets replies, etc, because he keeps doing it.
In the meantime, I get all his damn email. Usually, I’ll try to contact the company and get off the list, but he usually just signs right back up. At that point, I’ll request the password (which comes to my email) and then I will change the password and suspend the account.
Did you look at the link? Can you explain why you wouldn’t trust a link that goes to link.jdate.com? What’s in that URL that makes you suspicious?
My guess is that (like Orionizer alluded to) 141808864 signed up with your mom’s email address for whatever reason. Probably a typo. Apparently I can’t access JDate at work but I wonder if you could contact 141808864 without having to sign up for an account yourself? If not, I’m sure JDate has some kind of Contact Us link on their homepage.
