When I create an event on FB it’s easiest for me to just invite everyone, but two friends messaged me today asking to be removed from my announcement list. They live far from me and aren’t going to attend any of my events. I found a really easy solution from CIO.com that requires my friends to take action, but it should work great. How to block annoying Facebook invitations without blocking your friends.
Log into your Facebook account and choose “Privacy Settings” from the drop-down menu at the top. Next, click “Manage Blocking” next to the last option, “Blocked People and Apps.” This will bring you to the settings page for adding friends to your restricted list and blocking Facebook users, as well as blocking app and event invites.
