I don't get it? Are you concerned she and her followers will ruin things for other Americans exposed to the show?

I've vaguely heard of《这就是街舞》and it has been pretty popular in China. Haven't watched it myself though. Wang Yibo's "canon pair" isn't on the show though, so not sure there's much of the yaoi element involved for RPF.

Also, MDZS had all the elements that attracts the typical HP/PoT/yaoi fangirl fanbase, and a following in China that was significant even before it exploded with the TV adaptations. It likely would've gone popular in the west at some point, with or without the involvement of any specific BNF.
