> They also need to ban merchants from hounding me to review their products. One of them even called me on my phone. I don't know how they got my number.

If you go into the "Address Book" in your account settings, you'll see a phone number listed with each of your addresses. I'm assuming that gets passed along to merchants with your order details.

I report any merchants who make unsolicited contact. It's extremely annoying/invasive, especially when they abuse your phone number.
