Spammers have unfortunately devised a new way to invade phones: calendar invitations.
A rash of calendar spam has invaded iPhones in recent weeks as many people are getting a wave of calendar invitations from Chinese email addresses, which are sending annoying notifications.
Dear Apple, how to prevent these unsolicited Apple iCalendar event invites from Chinese spammers about deals on Ray-Ban glasses? #iCalSpam
