Counter point. Correct me if I'm wrong but the first tweet I see of the 100m Dance Practice was January 5th, which wouldn't explain the random 1m increase from the 26th to the 30th, when their views were in a consistent range for weeks beforehand.
I'm not saying that there wasn't an increase in fan views to get it to 100m for the dance practice, but from the 26th/27th of December up until it hit 100m it had another ad campaign to help it along.
Because it’s almost at 100m and they initially wanted to beat the record, until sm posted the poll, from that they just wanted content more than anything lol.
