The biggest use case of MOONs is right in front of your eyes!

If you've played any sort of online video games, you'd understand this in an instant.

People are social beings and we tend to show off our individuality and achievements.

Jewelry for example is used to show off how much money we've made. It's a status symbol.That derives most of Gold's value.

But in the digital world, like games, social media, etc. We have "High level stats" such as level 100 Mage, Assassin etc. Recently it's replaced more by in-game cosmetic items like Weapon skins and character skins.

In social media, we have the "verified" tick, follower count, etc.

It sounds trivial but people assign value to all of these things.

Now, MOONs being visible next to our usernames mean one thing and Reddit knows it. It's an indicator of how much you've participated or hold a stake of in this community. This visual representation is like a status indicator. It acts like a In-game cosmetic item.

As the moons/karma ratio goes down every month. The value of this status will increase as it gets harder to reach higher levels.

Since the community is large with 3.3 million subscribers, this visual status has some significance and Reddit Admins know it. That's why they probably have decided not to hide it.
