I have been asked this question plenty of times so I'd just thought I'd put it in writing here...
Honestly I don't care for badges...I don't feel the need to say I like XYZ idol or group because I know the groups who I like and the music that I listen to
I don't feel the need to have a DP or signature because again I don't care for them
I guess that might stem from me not being that invested in the groups I do like...so I feel no need to show them off or to promote them or have their gifs or photos on my profile...I guess I'm a bad kpop fan lol
I'm also lazy and can't be bothered with changing or adding photos or gifs or signature line...
although I also have no current need for akorns I also don't need to spend akorns for badges which are purely cosmetic...even in games and stuff I always go with the default skin or default avatar...
I guess I'm unique this way...(or maybe I'm just an old boomer geezer)
