"Maybe" is not an invitation for harassment

If you are trying to convince a friend to see a movie with you, and they respond, "maybe," you will likely ask them again in a few days. But facebook is a little different. First of all, if you are using a Fan Page to create events, you are already better off. You do not have the option of messaging all of your guests. Also, it looks more professional (I will not stop saying this) to come from an official page than a random user. But if for whatever reason, you are still using personal pages to create large scale events, you can still Message All Guests. Just because you can does not mean you should. I can walk into a bank and light the contents of the vault on fire. That doesn't mean I should. There are very few situations that warrant all-guest messages. A last-second reminder is appropriate. Notice that I said "a." That means one. Do not send one a day for the week leading up to the event. Also, remember that any changes you make to the event will send notifications to attendees. If you change the time of the event, you do not need to message the guests to let them know it happened. They know. But the single worst abuse of Message All Guests is the use of Message All "Maybe" Guests. If a person marks "maybe," you are right in thinking they will probably forget it is happening. But sending them a reminder is only going to upset the bulk of them. Those who were planning on attending but marked "maybe" will now consider not attending. Those who forgot or weren't planning on coming still will not attend. And those who were on the fence the whole time will be irritated and swing towards the negative side. Guests do not want a stranger harassing them on facebook. Just don't do it.
