No, you don’t need that. You’re not a nsf.com customer.
“nsf” means “notifications service”, which is a website used to alert you that a friend has emailed you a link to a book. “nsf” is an abbreviation for “no service for fucks found on the Internet”. This is usually because your friend has been hacked, so you’re getting a nsf alert saying that a friend has sent you a nsf link to some book.
The problem is that if you have an account with nsf, that means you have an account with that service. So if you dont have an account with nsf, the system will say that you have an account with that service and that you are getting a nsf alert.
In a way it’s a little creepy, because you have to believe that the author of the link has a good reason for sending you a link. But because it’s so creepy, that’s actually probably not a problem. If you think that you’re being hacked, then you should probably just go ahead and delete the link.
Because nsf can be used for evil reasons. I have no idea if this was the case here, but it is a good reason to stay away from nsf.
Because if you are using nsf you are probably using a 3rd party who is sending you a nsf alert. And because nsf is a 3rd party service, you can be sure that it can be used to do bad things. As I said, the checks can be used for evil reasons, but it is definitely possible you are using a 3rd party service that sends you a nsf alert.
In our case, we were notified that our bank’s website was using nsf and we found that the checks we were receiving were actually using nsf. We can only guess that we were using this 3rd party service but we feel pretty confident now that it was not the source of our problem.
While it’s very possible that you were using a 3rd party service that sent you a nsf alert, I would not recommend it. Instead, I’d recommend that you use a good 3rd party service like the ones listed on the top of this page that are not involved with nsf.
