With the recent update of MoonKarts, where the maximum points you can get in a race is now only 10 pts from the 15 pts before and that there is no way for you to run two accounts in one computer, it seems to be one of the reasons why the ranking points has decreased lately. With that being said, we've seen new names in the list. This is being because they got more time to play for the game.
New names have come in this Season 32, with names like edge1977, yuno.raize, lmcqueen95, etc have been playing a lot lately. They have been placed significantly in the Ranked leaderboards. However, it is completely different when you play at Orbitals Leaderboards as you need fuel and a good Fuel setup to compete in this category. This is also the leaderboards with the best prizes, approximately around 500-550k Colony is allocated for Orbitals leaderboard every season.
So right now, the rules have changes, it is difficult to play two accounts in one computer anymore even though you have a dual screen. One of the reasons for it is that there is an update that if your account doesn't move within 30 seconds, that account will get booted out in the race and face 4-hour ban.
The same thing has happened in disconnections, if you disconnect the race or even just leave the lobby a couple of times, it will get you 4-hour ban. This is a great measure especially to those that are trying to manipulate matches. It is definitely a defining moment of MoonKarts as players have played matches all along.
