I've just found further proof that the 'free ipod' scheme I outlined in an earlier post is genuine and not a scam. The BBC Newsnight programme did a report into these schemes which you can find here or it's readily available on youtube (search for 'bbc newsnight ipod) proving they actually work.
I have also found another great forum about these free gift referral sites - exceem. This forum has loads of information and tips about how to earn free gifts from referral sites and is a busy and well used forum. There is also a section where people who have received their free ipod (or other gifts) post proof of getting the ipod and share their experiences.
I'm still working on getting my free ipod from here. Thanks to anyone who has already signed up - if you're considering registering to get your own, please do it under my link: Get a free ipod from ipods giveaway!
Referral marketing sounds an awful lot like pyramid selling
