Getting nsfw comments in mom's insta page.. feeling angry and sad... idk what to do

This is a real post i dont want internet points thats why im using my throwaway. Pls help or suggest what i should do

long story short, mom has been uploading dance reels on insta for the last 3 months. I manage her acc and upload her vids

Till last month she used to get 4-5k views on avg and the comments were really supportive and respectful. In all those reels she was dressed extremely conservatively. Now 2-3 weeks ago her friend had gifted her a saree with sleeveless blouse. She doesnt wear sleeveless but i wanted her to get out of that conservative mindset so i encouraged her to try it out and told her to make a reel in it. Later she agreed and made a reel with it. Now i dont record those videos. She uses a tripod to record it herself and just asks me to add audio after taking video so i dont usually watch her videos, i just add the song and upload it. This week i saw that her reel started getting attraction and it has nearly 500k+ views. But now started the real nightmare

i first noticed a comment which was extremely filthy i dont even wanna type it out..in that reel while dancing there were few steps where she had to raise her hands thus her pits were visible and in between her sarees pallu got a bit sidewards and her belly was visible for a few seconds which is a totally normal thing but these creeps on insta started sexu@lizing her and commenting things like "youre such a mil f", "i wanna eat those p!ts so bad", "can i l!ck your n@vel" eww wtf these are some of the real comments which i had to read. In dms there were even extreme stuffs. I felt extremely angry reading those but then i remembered i was the one who told her to wear it and now because of me shes being sexualized. Idk what to do. im thinking to delete that reel but shes so happy that it got 500k+ views. She hasnt seen all those comments she just saw one comment where a person said "madamji aapke armp!ts acche lage aise hi sleeveless me dala karo videos love you" and she asked me what it meant. Shes extremely innocent and naive so i just told her hes complimenting your armpits in a good way else if i told her the reality she would become extremely sad and might even stop uploading. Now i deleted everything(comments, dms etc) before she sees more but im sure many more comments and dms would still come.She has 6k followers currently. What do i do. And the guilt that i am the reason behind this is eating me up.
