I received a SPAM calendar invite yesterday, never seen anything like this before and was dismayed that I was unable to delete the invite without declining the meeting. The invite was obviously spam for sunglasses. I did some research and found quite a few people having the same problem but only with the most recent iOS 10.11. There appear to be some work arounds but I'm not sure if they are all 100% effective. The calendar invites also don't appear to be attached to an email, they look like they're coming from the iCloud calendar. There are people also having similar issues with spam photo sharing invites and spam reminders, all again with NO way to simply delete the invite without declining, because once you decline you send a message back confirming your email address.
I looked on the beta forums but didn't see any mention of a fix in the pipeline for this, has anybody else had a similar experience? Is there a known fix for this behavior?
