Interesting that the "scholarship" (free) plan isn't mentioned on the homepage. It seems you have to try and steal the product before being offered the free plan. I also like the subtle dig, "if you can't afford it." I've certainly pirated things myself. If iTunes asked me, "We noticed you've pirated The Walking Dead. If you can't afford $3, click here to get it for free." By reframing it as charity I might be shamed…
"Hi, buddy! We noticed that you created five dummy accounts in order to get access to our referral reward. Thank you for your interest. If $1.66 per month or $0.05 is too much money for you to afford at the moment and it would prevent you from having a roof over your head and feeding yourself but would still like to sell your music and make a living in pursuing your dreams of being paid for your art and work, then you should check out our scholarship account. We believe in our community and are you are a good person that would not like it if people didn't pay you for your work so we are confident you wouldn't do the same to us."
Or is that too much?
