Is there a way to stop a specific person from sending you event invitations without removing them as a friend on Facebook? If it isn't built in, perhaps there is an application that lets you remove yourself from events after you are invited?
You should be able to stop receiving Event Invites by following these steps:
- Go to Manage Blocking
- Add persona non grata to Block invites from.
Once you block event invites from someone, you'll automatically ignore future event requests from that friend.
For a page that allows you to see everyone who's currently blocked in one way or another (event invites, app invites, totally blocked, etc.) and allows you to add more people to block, currently this URL works like a charm: https://www.facebook.com/settings?tab=blocking
Try this Chrome extension called "Facebook Invitations Blocker" to block all invitations (Like pages, Join events and try Apps).
