some streamers have this already & as usual, it's opt-in by default
If you are opted into this (unsure if any notifications were sent, they usually aren't) then you can disable it in your creator dashboard under Settings - Stream
If it's not active on your channel the option won't be there
It's always important to remember that NSFW is not a moral judgement, it's about how much side eye am I getting from my manager if they see it on my screen.
Once again reminding the community to please tag your lewds. "But no breasts/genitalia were showing." I'd argue that a miniscule piece of fabric covering the nipples/groin does not make it SFW... would you feel comfortable showing that to a coworker? If not, please tag it. Takes only a few seconds.
