There are a lot of twitch girls with camming past. ibabyrainbow being one of them. Sasha Grey being an ex porn star, Mia Malkova is an active porn star, Melina Goranson cammed, The twitch streamer who broke her back at twitch con Adriana Chechik is a porn star. Novaru cammed as well. Probably a whole lot more.
Kaho Shibuya used to be one of the biggest JAV stars along with Anri Okita. Kaho is featured on numerous very large Youtube channels, has great English and mostly just does cosplay and streaming now. Anri still has an OnlyFans but doesn't do hardcore stuff. Bonnie always came off a bit... strange. I knew her past was fucked up but not "refugee pressured into sex work to support her family after her Father abandoned them" bad. Seems like she's genuinely trying to make it on Twitch and do the things she enjoys, so good for her.
Dont forget a lot of these fans or people are zoomies. Or just got turned on by their content.
