Rating messages (+ or -)

The database system already serves to evaluate messages. There is no point in hiding messages that have received many downvotes: in most cases, such messages violate the forum rules and should simply be deleted by moderators. However, going to the other extreme and adding some kind of badge or medal to a message that has received many upvotes... In principle, why not. But it's not that important. I suspect that implementing something like this will take a lot of time, which would be better spent on some kind of chat or similar features.
