that took place prior to 2012 or early 2012 at latest. songs in 2008 could hit 5million downloads like big bangs haruharu. it was already changed by 2012.
[*You don’t have to answer again if this is getting annoying, but I have to clarify*]
No it must be in 2013. I can’t read Korean to find the information, but I found two old AKP threads where they also mention „after 2012“:

https://www.allkpop.com/forum/…million-downloads.236196/
Well now, looking back when in 2012 Crash got to #17 on the charts with 600k downloads, then in 2013 One Shot got to the same #17 with 284k! (And in 2014 the song 1004 got to #9 with 291k means, two years earlier this would have been almost double numbers).
So in the end B.A.P. weren’t really declining before the lawsuit, it was an overall problem with download numbers!
(The difference between 2008 & 2012 is another story).
