Twitch is now allowing "artistic nudity" and other stuff that's cool.
I'll believe any of their standards when I see it applied to both men and women.
If Twitch is going to allow some girl with huge boobs that are slathered in baby oil, then I want the male equivalent — buff fighting games streamer wearing boxing shorts where you can just see a tiny hint of shaft.
Otherwise it's just thinly veiled "we'll allow these streamers to break the rules because it makes us money!"
