This is probably in the wrong forum as your not selling anything. I've reported it so it should be moved soon.
I don't think you were punished for success, a lot of people use the same argument when they make too much money on PayPal and then decide to claim PayPal was in the wrong for asking where the money came from. At the end of the day it's Amazon's terms of service. Maybe post your site so we can review it?
I am not clear on how that could be, since I succeeded – I made a sale.
Just because you made a sale doesn't mean your content was original or unique. Seen those terrible eBooks that promise $300 per day sitting from home? Their content is all copied and pasted but they still trick hundreds of people each day.
I am sorely disappointed – I am a long time Amazon customer, and I looked forward to working with them as a business partner. They have made it clear they dont need my business, or yours.
You're right, they don't need your business. One person not working with them won't affect them at all, sorry to sound harsh but they have millions of others.
