Why Starship does not allow IVE TikTok to challenge other idols?

In case people don't know, other name for Starship is Starshit.

Wonder what people that claim IVE is part of Kakao think of that.. curious that they arent even allowed to interact with other Kakao groups unless its from Starship lol

Maybe to keep them "exclusive". It's a power thing, maybe Starshit thinks doing tiktok challenges for other artists' songs is "beneath" Ive. They probably want folks to start thinking of Ive as the next BTS or BP.

Which brings up an interesting question...has BTS or BP ever done a tiktok challenge of another group's song?
