Have you ever tried unsubscribe to Spam or Spam? If you did not try it good you would never do it. If you open spam emails you will notice that they also contain a link to delete your email from the list.
Don't think it's nice because it's not. The spammers didn't add the deletion link because they thought it might bother you. Nor did they realize that some people will never respond, so they try to narrow down their lists for more efficiency.
Clicking "Unsubscribe" or Unsubscribe in a spam email will make a very big mistake. The results will be completely opposite to what you expect.
Let's see why:
While "legitimate companies" seem to respect them requests διαγραφής του κάθε παραλήπτη, οι κακόβουλοι χρήστες χρησιμοποιούν τα links διαγραφής για να επιβεβαιώσουν τη διεύθυνσή σας και να σας στείλουν περισσότερα ανεπιθύμητα messages.
Her Alan Zeichick Sophos states that clicking unsubscribe tells the sender that you opened their email, possibly because you were interested or because you might have imagined the spam was real.
By visiting the fake deletion page that the spammer has created, you are giving him information about the browser you are using, the operating system, but also your IP address, risking even more and more targeted malware attacks.
If an email post officelooks like spam, don't click any links. Just mark it as spam and send it straight to your junk folder.
