The term "virtual youtubers" was only coined because of the major industry pioneer Kizuna Ai, whose kayfabe was being an AI. Hence, "virtual". This fact alone shows the vast majority of the so-called "viewers" here and in fact tourists. It's especially telling how ironic weebs call vshojo talents "virtual youtubers" despite the fact that not only they aren't "virtual", but they are actually glorified fleshtubers with twitch culture that have willingly shown their audience a large amount of skin, nullifying the need for an avatar.

Stop using terms you don't understand.
