Twitch is effectively banning the “topless meta” and other implied nudity streams with another update to its attire policy.

Under the new policy, announced on Wednesday, streamers are no longer permitted to “imply or suggest that they are fully or partially nude,” and may not show a visible outline of their genitals, even if they’re covered. Covering breasts or genitals with objects or censor bars to suggest nudity is also prohibited. Female-presenting streamers may show cleavage, as long as their nipples and underbust are covered, and “it is clear that the streamer is wearing clothing.”
