Amazon.com also has a tendency to combine different (but related, sort of) products into the same page as different "sizes" or "styles" supposedly of the same product. Reviews from all of these are merged, as are the Questions & Answers. For a current example, https://smile.amazon.com/gp/product/B0056OUTBK/ref=oh_aui_detailpage_o06_s00 https://smile.amazon.com/gp/product/B0056OUTBK/ref=oh_aui_de... combines listings for computer cases in a variety of tower and rackmount sizes, server racks, drawers, and rails. Separate items all available as options on this page. For reviews, Amazon now labels them with the "style", i.e. one review is for the "Server Rails" style, while another is for the "Server Case" style (though there are a half dozen different "Server Case" style items on the page, each with different characteristics). Questions & Answers are just a free-for-all that requires humans to sift through context and figure out which product is actually being discussed. One of the questions on the linked product page, ironically asks, "Do I need rails to mount this in a rack?" It's a complicated question to answer because the question could have been posed about one of the many 2U or 4U cases ("yes", unless maybe one of them ships with rails) or it could have been asked about a tower case ("no, this isn't rack-mountable"), or it could have been asked about the rails or the rack themselves (as humans, we screen these possibilities out by context and logic), or about the shelves offered (not a completely unreasonable question -- maybe a shelf could be sold without rails?). Or if we're not so observant, we click Buy after reading Q&A and reviews, only to later learn that we bought a different "style."
