Public apologies by BTS fans who spread rumors
ARMY who originally spread the rumor stepped forward and posted an apology letter:

“First of all, I have nothing to say except that I am sorry. I had posted an unconfirmed story about Spotify around 12 AM last night, and more people than I had imagined ended up misunderstanding the situation. I knew that it was not true, but I just left a short message and did not cope with the troubles. I found out later, but the screenshots that I had found (of the Black Pink ads before BTS’ music) were also Photoshopped and were fake. I did not even think to check if those pictures and stories I read on various online communities, and went ahead and posted it here. Because of my act, many Blinks and the innocent members of Black Pink were extremely criticized. I am sorry. I initially did not have any intention of wrongfully accusing Black Pink and Blinks.”

1.[+307, -285] I feel so bad for Blackpink… When BTS first debuted, they also media-played as ‘second BIGBANG’ and ‘second EXO’

2. [+233, -306] BTS fans posted another post that got more than 500 likes to claim that Apple Music and Spotify must be doing sajaegi since Melon does sajaegi too ㅋㅋㅋ When another artist gets higher digital sales, it’s a sajaegi ㅋㅋㅋㅋ

3. [+229, -229] They are #3 on USA Youtube, why are people still mentioning Southeast Asia

4. [+128, -126] Don’t live like that just because you’re crazy over men
5. [+108, -22] I wonder why they # 300 on Apple Music? If they’re doing well, shouldn’t their ranks go up on all charts?
