>>15544664NTA, but the numberfagging you're speaking off is stupid /#/ shit like Pekora vs Gura, Holo vs Niji...etc.
The general public does numberfag big numbers, like "oh shit we got 100k people in here!" and it definitely does drive more excitement and hype.
Youtubers are more likely to click on VODs and clips with more views than less views, it's one of the things that drives the algorithm.
If anything, their numberfagging is potentially dangerous since they only notice big numbers and they might overreact to regressions to means.
Like Fubuki casuals might actually think she reclined if her median is back to 12k next month.
