Send message to a non-friend facebook user?

Question

I am developing a Facebook application. It must notify random people on Facebook about a certain event that happens related to them. I mean random people - not just those who installed the app, that's a key point.

Yeah I know it sounds like a spammy annoying application, but I swear, it's not that kind that everyone hates. :)

Is there a way to send anything (wall post? message?) to a user that did not previously installed the app?

Answer 1

No, that's not possible as per facebook's privacy policy. There should be some sort of connection like friendship/application user to do this.

Answer 2

It is possible, but only if you direct the acting user to the send message URL in a new window. If you are talking about an automated way, it is not technically possible at the moment.
