Only keep active players on the leaderboard

I agree, but there has been changes to the FFA leaderboard since the teams were released. I was ranked #7, now I am ranked #10. I saw @hest1805 play a game about 3 days ago when he was slightly rated above 2000 and somehow got paired with a 1900 player and 2 1800 players, something that is very rare.
I did want to sit on my rating for a few days before playing again, but the main reason I have not played for this long is that I focus on the teams variant and that I don't think I can get good pairings in FFA.

@trinhlan got to the top of the leaderboard only by cheating. That just leaves two players who have made any impression on the leaderboard since teams were released, out of which one is a GM. Removing inactive players from the leadboard will encourage all the top FFA players to play more, and as a result, the chances of bad pairings would also be reduced

Notice nobody from the leaderboard has commented..?
Guys, chess.com is a website, not a granite stone. That means: We don't need to remove something old to add something new!!! There is enough place for 2, 3 or 33 leaderboards. Seriously.
Chess.com can make tabs in the leaderboard list:
Today's Leaders,
This Week Leaders,
This Month Leaders,
This Quarter Leaders,
This Year Leaders,
All The Time Leaders,
This Minute Leaders,
The Leaders Of All Week End Games,
etc.
Why not?!
Do not remove anything. Want to show the weekly top players at the main page - go ahead and show them as the main list. But do not remove the old list, show it on the 2nd tab if you wish, but do not remove.
Again. It is not a granite stone. It is a website.
P.S.
Just checked the FFA leaderboard, I am still number 9. And I do not play FFA for 2 reasons:
1. The Teams Mode attracts me much more at this particular moment.
2. I do not like that I can lose 90 points in a single FFA game. So I wait till battleMind24 will change the rating system to make it more mild and adequate (for example, divide the rating changes by 3). He promised to switch it to Glicko rating system too more than 1 month ago.
I noticed that a player on the top 5 bullet or blitz leaderboard on the chess.com main page will get removed if they don’t play any games over a 1 or 2 week period. They’ll still appear on the global leaderboard, but on the main page, only players who have played a game over the past week or two will be shown.
Why not do the same for the 4 player leaderboard? The FFA top 15 has remained stagnant for quite a while now, and even in teams, some of the players who got on the leaderboard aren’t playing anymore just to stay on it.
