Get a free iPod by helping me

I know a lot of people read this site, and I wonder if you guys can help me. I am trying to get a free iPod, and just by having 5 of you sign up for one offer I can get it. For example, by getting this Blockbuster trial, you sign up and cancel before your 2-week trial is over, and I already get it. And if you refer 5 friends you can also get your iPod for free.

If you can help me, here is the link for free iPods
