iPhone Calendar phishing invitations sent by email

I'm now getting daily phishing attempts via spam email. The phishing emails contain a calendar event that automatically shows up 1) on my calendar and 2) in my calendar inbox. I have this happening via two completely different email accounts. Anti-spam is working fine on these accounts - mails go straight into Junk. Where Apple totally screws this up is:

1) It accepts the invitation for processing regardless of whether the originating email goes into the junk folder

2) It doesn't allow any configuration of either email or calendar to prevent processing of calendar events

3) It does not allow deletion of the invitation or event - only Accept, Decline, or Maybe. Any of which will send a notification to the scammer that they have a live target.

I did call Apple support on this, and the agent said that Apple knows of the problem but not what to do about it, which I found odd. They recommended that I either 1) Decline or 2) Wait for them to disappear because they are time sensitive. I don't trust 1) and with 2) this worked until the most recent batch which are not expiring and collecting in my Calendar.

And then there is this unhelpful link:

support.apple.com/en-us/102444

Which is garbage - THERE IS NO DELETE

Also regarding instructions regarding Calendar - it's my default calendar that's being attacked. No I can't delete it or turn it off.

This does not seem to be rocket science. Why can't calendar invitations be deleted? Why don't settings allow auto-inclusion as an option rather than default behavior? Why not be sure that the mail is in the Inbox and not Junk prior to processing the invitation? This is extremely sloppy security.

Am I the only one with this problem? Is there a clever way around it? Is there a known bug report/feature request I can pile onto?
