I'm guessing that's because Amazon sends out emails explicitly asking people to answer questions on their past purchases. And for some reason, this makes some subset of people feel obligated to reply even though it makes no sense.

I think you're right. That sounds exactly like something amazon would do and how people would respond. I must have turned those emails off, which makes seeing the answers utterly stupefying.

To give customers the benefit of the doubt: Some may know exactly what's going on, and enjoy making Amazon look stupid by posting those replies.

That reply doesn’t suit your handle at all ;)

Amazon sent me questions about a product I gave a one star review to. I really should have sent it back.

Their system isn’t too bright.

It's because Amazon emails everyone (who bought that product) every time someone asks a question. The subject is "John Doe: Can you answer this question about ...". I've had this email a few times. Some people (I'm guessing old/non-tech savvy) assume someone has asked them directly, and so feel the need to reply.

That makes sense. The answers I refer to read just like a slightly annoyed text message reply to a family member who should know better than to ask.

My personal favourite is "I bought this three years ago and don't have it anymore. I don't remember."

I always find it sort of charming and refreshing when people respond as if it was a face-to-face conversation
