Sell outs & chart manipulation
The rappers (namely RM and Suga) were first called sell outs for being in a K-pop group
Because K-pop is too mainstream.
The rappers tried to explain that they wanted to get their name out there by joining a company but was told that they were only chasing the money.
Now they only chasing the Grammy
They were first accused of chart manipulation because it was absurd that a nugu group like BTS could sell that many albums
Their logic :
"The company must be buying the albums in bulk because they don't really have that many fans. I smell sajaegi!"
Now they got too many fans manipulating the charts by buying in bulk
