I'm pretty sure craigslist would catch on fast, since the IP's are almost always the same and you'd be posting in a different country than the IP. You would probably have better luck going on warez-bb.org and offering the kids there rapidshare accounts in exchange for making a post for you. If you look around you'll be able to find rapidshare accounts that are generated from bonus points for about $3-4 each and split them between 5 people.
