Up- and downvoting are ment to be opinion based. You are supposed to upvote what you like and downvote what you don't like. Things like spam, or other things that are against the rules are ment to be reported. The reason for this is that the report will reach a moderator, but a moderator has no way to automatically be notified whenever you downvote something.
