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.
If you click “Unsubscribe” or Unsubscribe in an unsolicited email you will make a very big mistake. The Results they will be completely opposite of what you expect.
Let's see why:
While "legitimate companies" appear to respect each recipient's unsubscribe requests, malicious users use the unsubscribe links to confirm your address and send you more spam 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 delete page that the spammer has created, you are giving him program information tourwhich you use, your operating system, but also your IP address, risking even more and more targeted malware attacks.
If an email looks like an unwanted message, do not click on any link. Simply mark it as spam and immediately send it to your spam folder.
