>>17697362eeh, I still think you're overreacting and doomposting about things that haven't yet and will probably never happen.
If the KR clipper does good work, let them get their shoutout, why not. It's not like she hasn't shouted out, liked and even commissioned all her other usual clippers before, and it's not like she will never do so again.
fwiw, the korean in her chat is already simmered down to a pretty manageable degree, outside of special events like Kronii language teaching or Snackbox stream it's just a few lines here and there and no non-KRs would feel intimidated or turned of by their minor presence (unless you're a special kind of sissy schizo).
Whatever it is that you have imagined in your head about how the dastardly gooks will take over and ruin her for everyone else is pretty much tilting at windmills. If it soothes you, I can tell you that she will most likely not actually seriously learn korean, for example, even if just for the simple fact that Netflix and catcuddles are a more alluring way for her to spend free time.
