If you haven’t yet experienced receiving unwanted even invitations, a.k.a. spam, on your iPhone or iPad’s Calendar app, consider yourself one of the lucky ones. iOS users have reported suddenly being plagued by numerous such invites on their devices, and declining them seems to make it actually worse.

But as spam filtering only happens on Apple’s end (for now), all that users can do is wait and use these workarounds to get rid of those notifications (for now).
