Just saw this tweet under Vei's art tag.
https://twitter.com/Holo_Data/status/1443848162150658065 Can't read Japanese but Google translate makes it seem like the most watched vtubers or something, and Vei, Mouse, and Nyan are on it. What makes it really weird is that the account is called Holo_data so it's weird that they'd be tracked at all in whatever this is
