I tried post my banner on facebook but I could only figure out how to send it to people who are my friends. I dont use facebook so I don't even know if they have ads like myspace.
check facebook PPC / CPM: http://www.facebook.com/FacebookAds or, from Fiverr or other sites, you can pay someone, who has huge number of fans, to post on wall and message friends
Facebook Ads without conscious they will not know your friend link. and they must have seen had you,,, I also equal wear on facebook thank you friend who I knew only that
