I'm from Germany. Last week I received a mail from amazon referring to the IRS. They want several personal data for (!) IRS!
I sell only my own old books via amazon. Last year only 8 sales with an total amount of 24$! I sell only in Germany! I never shipped one item to international customers. My shop is only national! I wrote this to amazon, but they still want my personal data for the IRS!
I'm German and I have absolutely no relations to the US. This IS Big Brother and it is dangerous. I wrote to my government and send the amazon mails to them...still waiting for an answer.
