Why IMDB Change Rating Method for Just One Movie "The Kashmir Files" ? IMDB Made fraud & Cheat with Movie "The Kashmir Files"

I had given my review to on imdb for movie "The Kashmir Files". it's 10/10 and even most of people given review to The Kashmir File as 10/10. 

and after 2-3 days of release The Kashmir Files Movie IMDB change methodology of average rating count did change for just 1 movie which 

is "The Kashmir Files" and it's rating change 8.3/10 instead of 10/10. 

it's indicates IMDB Must control or force by Bollywood Mafia which is not interest to release this movie.

Now i have many question and i had many reason to IMDb is untrusted for Movie Rating. and i request to all people Please,

Don't trust on IMDb it's not trust worthy, it's handle by mafia, in Rating of Bollywood Movie it's totally handle by Bollywood Mafia,

and all people know who's Bollywood Mafia.

I had dam sure this issue must be deleted by IMDb also.
