I figured it must be patented because it hasn't been mentioned yet, but you could implement a cost to sending messages to people outside of your mutual friend/fleet list, or something like. By default it can cost 1energy or so, but it seems it would cut into spammers profit margin significantly, while impacting normal users almost 0. I have seen this implemented only once before (I don't really play many MMO) and it worked pretty durn well there.
