I don't. The whole thing is stupid. Besides the actual supporting the artist, fandoms are all toxic and mindless. As soon as you become a fan, criticisms towards those artist are no longer able to be said. Crossing fandoms is barely acceptable, cause if you don't just "love" one group you aren't a real fan. Other people feel like they have the right to tell you how to be a fan. I can go on and on. For example, when I say Jin is lucky to be in BTS, armies will attack me. Like I am not a fan too. He is lucky. He isn't a good dancer, and their genre is completely not his style. For him to be in that group is luck. Does that mean I hate Jin? No. Does that mean that I wish him to leave the group? of course not. It just a blunt observation. Similar with Bora's lack of rapping skill. Does that mean I love her less? No, I love her regardless of her very subpar rapping. Does that make me less of a Sistar fan? HA, I have all of their albums and know all of their songs and have seen all of their dramas and web dramas. Again, it just a blunt observation. But being in a fandom......grrrr. Fandoms are the worst part of K-pop. Even worse than western fanclubs sans the Beyhive (they are just as bad)

"a fandom so tiring to keep up with" - Simple answer: You dont have to keep up if you dont want to. if it gets tiring/not enjoyable, take a step back :)

Fandoms do have benefits - lots of willing pple to give u info about a grp (cos my brain cant keep track of all that),

make subs T_T, get memes, donation projects, make friends.

(my fav. - help u find the name of a song from just a gif or a 10sec clip ^_^)

but nowadays, pple only notice the badside - spamming for views, insulting other groups to make their favs better, being unable to take criticism, etc

I'm a multifan (diehard VIP/MeU) [i've never understood the solo fan culture both b4 & after i entered kpop.]

so taking part in ALL fandom activities WILL drain me. I just chk out what i like, aka mostly news articles, or youtube clips/subs, & i leave. & that works for me :)
