How do I block spam calendar invitation emails?

This is very frustrating to have a calendar fill up automatically with sale adds. I let it go for a long time with one and as soon as I deleted it, it sent a declined notice and now I have had many more. Please add some spam filtering and an option to delete and remove your email from a calendar invite without declining.

I should also note that I am now getting icloud photo invitations for the same spam. Yippee...

This problem first appeared in iOS 10, because of a big error by Apple programmers.

Do not decline the invitation! If you select it and choose "decline", the spammer will know he’s got a live victim. You will see an alert that says:

If you decline this event, the originator will be notified. You can view declined events by choosing Show Declined Events from the View menu. You can’t undo this action.

Apple gives us no way to delete it without notification, so we need to use a trick. This appears to be the only way to delete it without sending an acknowledgement:

1 Make a new calendar.

2 Move the ad to the new calendar.

3 Delete the new calendar.

You will be presented with the option to delete it without informing the SPAMMER.

To keep this from happening again, fix the error in your mobile devices (iPhone and iPad). Go to Settings -> Calendar and turn off Events Found in Apps. (That's the mistake made by Apple programmers.)

Unfortunately, Apple has no solution yet to the iPhoto sharing error.

Now I am getting them in my reminders app :-(

Same for me. But in addition, i also receive requests to share my iCloud photo albums. It is happening now everyday. For calendars, I receive invites written in Chinese. I don't want to decline because it will send a decline mail to the requestor and he will have my full identity (name, surname etc). It only happens on my iCloud calendar (no gmail or other). Does this mean someone managed to get several iCloud accounts from a hack to apple servers ? This is quite worrying me.

In attachment, a screenshot of what I see (my phone is set up in French). These requests are polluting my calendar..

When I try this, I get a message that the sender will be notified. That seems like it validates my email. I've just parked in in my new iCloud SPAM Calendar and turned off that calendar. Please advise.

I tried what you said:

1 Make a new calendar.

2 Move the ad to the new calendar.

3 Delete the new calendar.

You will be presented with the option to delete it without informing the SPAMMER.

... but I don't get the option to delete the calendar without notifying the spammer. See? Can you help?

I'm using a MacBook Pro, OS 10.9.5

To Citre:

That message does not say anything about events to which you have been invited, only event that you have previously accepted, or that you organized (and would be cancelling by deleting the calendar). I think you should be fine by deleting that calendar with all the spam invites.

What an unbelievably stupid loophole/exploit to exist. I received one on my calendar and apparently stupidly declined it since that seemed like a logical thing to do, not realizing this idiotic loophole existed that would then make me a further target to more spam. I've received more in my calendar and have done the workaround to add it to a new calendar and delete that calendar, but am now receiving them in the Reminders app and see no way remove it without declining.

Completely unacceptable that this is happening, and there's not even a simple option on the user side to block incoming invites outright. Unbelievable.

Apple made the same stupid mistake Outlook made ages ago. They dont have the declined or deleted without notification function. I wonder whether Apple are still living in today's world.

They seems have no fix other than turning off iCloud calendar. They just render their iCloud calendar to be useless.

Yes, thank you!

At last a working soluton. Thanks!!!

Abit annoying there is no better apple solution and that you have to create and remove a new calendar each time. But it definitely works!

Same for me. Only appears in Calendar, nothing in mail app..

I'm getting the reminders stuff too which is so annoying!! Please Apple sort this out - it only started since the last update....!!! 😟

I was able to delete the invite but now the spammer appears in my invitees list whenever I go to create a new event. How do I remove it?
