No, that is sleazy as anything “growth hacking” from Amazon.

If you bought product X and some months or years later “Sam” posts a question on Amazon that isn’t answered, Amazon will send you an email with a subject line that is a variation of “Sam has a question for you about Product X, can you help?” and the body would be something along the lines of “Dear foo, Sam wants to know if <insert question regarding Product X here>? Click here to respond to Sam and help her out!”

In that context, you can easily see why people reply with such otherwise useless “answers.” When someone personally asks you a question you don’t know the answer to, responding with “sorry, I bought it for my husband as a gift and I don’t know,” is not just perfectly valid, it’s also the polite thing to do. But that answer is posted to the website in the genera Q&A as of you had viewed the question and then instead of passing on a question you had no answer for, you chose to reply with a useless answer.

Very interesting. I had not considered that possibility.

Occasionally AMZN will send out questions others have asked about products to you in the form of an email if you have previously purchased the same product. Some people mistake those for questions directly asked to them instead of realizing where their answer will be posted. StackOverflow doesn't do that AFAIK.

See my other reply. It’s not fair to even say the user is making a mistake; it’s Amazon purposely manipulating users into thinking they’re being personally asked a question to game their way into getting more answers.

Oh. I didn’t think of that. I’m too naïve. Thanks!
