Spam invites to events in the calendar

Try going to iCloud.com/Calendar. Click the gear at the bottom left and select Preferences. Click Advanced and click Invitations/E-mail to and add an email address.

You can also try creating a new calendar and add the invitations to that. Then either delete the calendar and uncheck it so it doesn't show.

So since Apple do not answer any of theses. And answering these invitation will send/confirm your email a potential spammer. I strongly suggest that you stop using iCloud calendar, you can integrate easily a Google Account in it and make the switch. I done it, the spam invites have stopped.

Unfortunately moving the spam events to a junk calendar does not work. Get an error message that only the sender can make changes. Apple needs to step up to the plate on this one.....

Calendar and Photos SPAM Invites

It seems like a simpler solution would be something similar to what exists in Outlook in the Windows world. In Outlook, when I receive an invitation that I don't want on my calendar but I also don't want to send the invitee a Decline, I just right-click and it brings up the option of declining without sending a reply. In that way, it's off of my calendar but a notice is not sent to the spammer. Seems like something Apple could do, if they just would....
