Yeah, there are a handful of (some retired) adult movie stars that stream on the site. I'm not sure how to distinguish the traditional adult movie stars from OnlyFans people in regards to this post, but for the "traditional" stars, they all seem super cheerful and friendly, and other than wearing tight-fitting shirts I don't know that any of them have done anything lewd at all. From what I can tell, they are good members of the overall Twitch community, same as tons of other people.
