On Wednesday twitch changed their site rules to allow artistic nudity. The policy allowed streams to display nonsexual nudity as long as the stream is tagged, so that the stream would be hidden from the front page. Twitch rescinded the policy 2 days later.
Twitch has a some streams that are literally a woman in body paint or pasties jumping for money. Some (not all) of the titty streamer complaints are about this, not women playing games in a swoop neck.
AFAIK the most recent rule changes don’t address this, it’s still allowed, but you can’t stream yourself drawing a naked person.
Doesn’t really fit into my point, but here’s the funniest ban during the brief window where drawn nudity was allowed: https://x.com/baalbuddy/status/1735397897242579068?s=20
