iPhone users - chances are you've received a calendar invite to "$19.99 Ray-Ban Sunglasses," or a "50%-off Ugg Boot" sale. Now while you may want to clear your calendar and take advantage of these incredible prices, unfortunately, they're fake. Here's how to get rid of them.

Don't know what I'm talking about? Consider yourself lucky. Millions of iPhone users who use Apple's iCloud Calendar have been receiving spam invites with dubious links in the description - taking advantage of what is supposed to be the useful feature of automatically populating your calendar with email invites.

So long as you don't use the link, you're safe. This isn't a hack of any sort - simply email spam, except the Calendar doesn't have spam controls like your inbox does. That means users have been bombarded with what is usually hidden away.

While the Cupertino-based Apple get to work on a fix for this, is there anything you can do in the meantime? Well, let's get one big piece of advice out the way.

Do NOT decline the invite

The logical fix is to just say "no" to the invites, right? Well, in doing that, you're notifying the spammer that your email is active. Users who did this reported receiving many more calendar invites after doing this.

To properly decline an invite without notifying the spammer, you need to create a new iCloud calendar inside your calendar app. Select "Calendars" at the bottom of the screen, tap "Edit" in the top left and add a new calendar under the iCloud subheading. Move all of your fake invites into this calendar and delete the whole calendar.
