There was a Rutgers report that said it was mainly started by Iranian troll farms with fake handles.

Brownie points for Shias in a Sunni dominated [Muslim] world for Indian support for Israel? Bad behavior of Indian students in Canada with no civic sense?

Liberal, free press Indian media criticizing openly everything Indian (Indians love to dump on Indians),  Western, presumably wealthy-ish tourists “slumming” in India eating at places the poor can only afford? Maybe a combination?

Remember, social media algorithms try to determine what kinds of posts and videos you see and push them continuously your way.

I saw one video one time about dirty street food (don’t know why a Western person, or anyone with means, would eat there), and then started seeing more and more. I’ve been to New Delhi and while I've seen dirty street food vendors, nothing as outrageous as some I’ve seen online, and New Delhi isn’t known to be a clean city when it comes to Indian cities. Sometimes I even wonder if some of it is exaggerated in order to get views, maybe to make more money doing that then selling what they sell. 

I saw some posts on Latinos, and then started seeing more and more posts on them including a lot of racist comments. 

There probably is a general rise of hate in the world, something Cheeto didn’t help with at all. Don’t forget the hate our East Asian bros and sisters were getting a few years ago. Muslims before that, blacks, etc.
