If you’re hosting a Facebook event, and you want someone to be excluded from it, there are a few steps you can take. The first step is to create an event page for the event. This will list all of the attendees, as well as any required information like their email address or phone number. Next, add a contact for the person who will be excluded. This should be someone who you trust and who will be able to handle communication with the person they’re excluding. Finally, add a message to the event page that says “This person is not allowed to attend this event.” This should be sent to all of the attendees who have RSVPed, as well as anyone who has added them as a friend.
