My chess ranking suddenly went up without rating improvement ???

I was looking at my ranking the other day, and i realise i went from 140K to 90K in the chess.com rapid ranking  without playing( my rating was the same around 1500) There is still the same amount of player in the ranking.

It is exactly the same with my bullet, blitz and daily ranking, does anybody got an explanation?

No that's to much , how about the ones which won games  ?

I know that it is a lot of people. But that was the only possibility. If you did not lose or gain rating points the number of players stayed the same. Then the only thing left is that all those people dropped.

Nope because 60,000 people would have mean all people between 1500 and 1750 to drop down 1500 and no wins for people under 1400 (which is impossible)

Maybe unactive account after one year ?

I think there had to be a computer error. I saw on a poll question that had 106% response. Which is impossible.
