How to stop spam calendar invites on your iPhone or iPad
We’re all very well aware of email spam. It’s something we’ve been living with for just as long as we’ve been using email and quite frankly, it’s not as bad as it used to be because email services such as Gmail are increasingly better at catching these messages before they even show in your inbox.
Recently a new kind of spamming has surfaced, and it relies on your iPhone, iPad, or Mac and iCloud calendar. The technique is actually pretty low tech, yet very clever. Chinese spammers send iCloud calendar invites to your email address which they probably scraped from some website, knowing that it will most likely trigger a notification on your iPhone and iPad.
If you accept the invite, your calendar will be filled with events promoting various products, usually fake Ray Ban or Oakley sunglasses. If you decline the invite, well, you just alerted the spammer that you did notice the invite and confirm the email address he sent the original invite to is active, pushing him to send you more and more invites.
It seems that no matter what you do, you lose. Fortunately, there are a couple things you can do to disable calendar invite spam on your iPhone, iPad, or Mac, and delete events you might have accepted.
