Apple Is Working on a Fix for iCloud Calendar Spam ⇥ twitter.com

Apple PR, in a statement to Rene Ritchie:

We are sorry that some of our users are receiving spam calendar invitations. We are actively working to address this issue by identifying and blocking suspicious senders and spam in the invites being sent.

I used to be getting a few invitations a day. I haven’t received a single spam invitation since Monday, even by email.
