I tried to send a friend a message in Facebook and this message popped up:
Based on the preferences of the person you're trying to contact, this message could not be delivered.
Does that mean my message was blocked?
I searched the Facebook help forums and found one other person had this same issue but didn't receive an answer or clarification

Yes, it means your message was blocked. As an experiment you could send again, it you do not receive the same message, it means the first set was a technical error with Facebook.
As Alex mentioned, sometimes there can be bounces.
