Artificially boosted chart placements
IU chart runs are legit ✔️
You're using Top 100 longevity and you're using Gaon instead of Melon. Gaon is too easily manipulated by fandoms, BTS has 10 songs that hit #1 on Gaon Weekly, but they only have 4 songs that hit #1 on Melon Daily (and maybe only 3 that hit #1 on Melon Weekly i dunno what Fake Love did). Also, dont forget that musty trot singer Lim Yang Wong got like 47 MILLION Gaon points in a week because of his fandom, Gaon just isnt reliable anymore.
Gosh, just stan BTS already you guys. You’ll get more satisfaction and be happier, I promise!
