Bigot put false hateful information all over bollywood film description

https://www.imdb.com/title/tt12861850/?ref_=ttkw_kw_tt

The film (Chandigarh Kare Aashiqui)

is about a relationship between a man and a trans-woman but some troll decided to change the description to a false narrative and mark multiple false tags like "crime against nature" and "evil"

How can imdb just let this happen?? Why is it this easy for someone to just post hate speech onto the site? I thought there was an approval process.
