It seems to me like there's a big market for sexual video game streamers. A site that came along and allowed it might even dethrone twitch if done well.
Video games, Twitch, and Boobs are all things teenage boys generally like, and they have a lot of free time to consume media. Im 100000% certain thats all this is all about, that that's the sole driving force behind all this. Nobody wants to say it but twitch is porn for kids
