It's better than Amazon or Google. I have had accounts shutdown on both with absolutely no recourse.
My Amazon account was banned because A buyer (I believe was a competitor) purchased an item and claimed it was a fake. I had proof it wasn't, but it didn't really matter. Other than this I had nearly 100% positive feedback. What's funny is that I now buy thousands of dollars per month for my business through Amazon and I keep getting pestered to sign up with a business account.
Google banned an Adsense account when they somehow thought I was faking clicks. I still have no idea where they got this from. My site was't even live yet and I wasn't clicking on anything or even displaying ads beyond a simple test page with no traffic.
