Nowadays, you cannot prevent anybody to srnd you message, despite whatever filtering you set.

Even if you don't shown Message button when someone look at your Timeline, they still can send you message.

What can we do is just block each person, I know, they make another account, and sent you another messages. That's annoying. But if only you who report it to FB as being a fake account, it's no use, unless you can prove it, but how; it's a lost lost battle, so just block & forget it.
