i used to love skz they were my ults but i had to unstan bc of the overwhelming amount of racism and stays kept defending them and dismissing blk stays it was extremely toxic.
I've never really full on stanned a group so I don't know if this counts, but I definitely remember at one point in time when Blinks just became too much for me and I just sort of stopped with the Blackpink content (still listen to their songs, though. They're bops). From what I've experienced, they're super toxic, not just towards other fandoms (as soon as they feel threatened that some other group's gonna "take their queens' crown", they charge), but to each other too. Like, I see a lot of them supporting only one member and completely hating on the rest. And don't even get me started on making comments that are any less than complete praise. You can't even give constructive criticism without getting a mountain of hate for "bashing their queen" and being "a jealous hater" or something.
Of course, this is just from what I've seen, though I know there are many more Blinks out there who aren't like this at all, and it sucks that just this small handful of people have not only ruined my experience with them, but ruined the image of the actual fandom as well.
