I was a hardcore Blackjack and 4Nia in 2012 but after a while I realized it was more like I stanned individual songs/albums/comebacks from loads of groups.
For 2NE1 they haven't released anything I've loved since 2011 which is when I got into them. Besides, there hasn't been anything to stan for in YEARS
For everyone else in my sig I love enough of their music to call myself a stan but I'm not into most of them non-musically.
