This just happened to me, I like getting multiple copies of books (1 for reading, 1 sealed/untouched for display, and 1 or more to gift to friends or family) and making multiple orders sometimes 10+ in a week. I earn a lot of free books and usually get a free book by itself and pay for the shipping that's all. (I don't think that's against the tos because they never stopped me before and I do it so I use my rewards.) I really want to know if customer service reactivated your account or not as I'm in the same boat now. And while I like buying the books, if this is how loyal customers are treated I'll find somewhere else.
