If you notice a snap has been downvoted, often you can tell why. At the top of the snap there is a bar, with up- and downvote buttons, that gives the vote total and also shows the number of up and downvotes. If you click or tap on the downvotes, you get a popover that gives any reasons that were given for downvotes. Worth mentioning, also, that you can specify why you downvoted a snap. If you go to a snap, and click the downvote button on that bar, a moment later right next to the downvote button will appear a ‘reason’ button that lets you select from a list. I gather that delay has something to do with a round trip to and from the site, so it's dependent on how busy the site is, but it will eventually appear.
