what do you think do you think compainies just go around saying hey lets just give $300 of merchadise to any one who wants it I think they posed people to look like they got one. Its probly like you get dumped with spam and junk.
It is indeed possible to get a free ipod through this sytem, you will of course need to generate 5 referrals to friends and you will obviously get put on a lot of mailing lists. If these costs are worth it (i.e. possibly having friends spend some money they didn't want to spend and dealing with blocking more spam) then it may be worth your time to try the service... personally it isn't for me.
