Long answer: On twitch gooner culture was STRONG and clippers like cooksie, who made many vtubers popular by clipping them saying cum or sex, were seen as bastions of vtubing fame, so every chuuba tried to goonify themselves to be clipped, I've seen chill vtubers turn into cum addicted whores just to get clips, don't get them and then cry about it
