^^ is her page. If you click on the photos they enlarge and you can see some of the comments. You'd have to have an account to see all of them.
Thank you. I did just that and I couldn't read most of the comments since they are in Russian/Korean. One comment (among several) in English says "F your mom." That is clearly disgusting and deplorable. Instagram should take action.
Edit: As I say this, I just saw a post saying "Korean's are inbred psycho." Well that user needs to be banned, too, I guess.
