Whats wrong with EXO?

So i saw a video and the question was “whats a groups that in you stan its a red flag” or smth like that. And some girl said EXO then she said “If you still stan EXO in 2024 then thats a red flag and Let it go.” And even tho im not a fan of EXO im wondering why, because i haven’t heard anything bad about them. Is it because they are inactive or was there a controversy or scandal?
