yeah man happens a lot on onlyfans. Iris Adamsone isn't a streamer but alot of the times these models go with agencies, the agencies set them up with everything like the chat people that are on 24/7, social media, etc., but if she is a streamer they will also provide her the Playstation/PC, mic, accessories, and sometimes even fake gameplay since some of them don't even play games like at all. There's a lot of money to be made so these companies will fake just about anything they can.
Unfortunately they usually got a boyfriend, they just won't say or mention it at all. Makes them more money to mislead fans into thinking they're single. Pretty sure Isabelle Harris is also with that same agency, but that's just my speculation. I could swear I've seen them film different solo videos/picture sets in the same place when they first started.
I've followed them on/off on Twitter since mid-2021 and it's apparent that they're part of an agency. Other girls that I think were with them are Ida, Scarlett Bee, Erika Song, Suri Snow, Keira Ko, and others (I think there were around 10 of them?). I also remember one instance where Iris posted the usual thirst trap on Twitter but on the comment linking to OF it was the template for Ida's posts. I pointed it out and a while later the post was deleted. In mid-2022 it seems their "group" broke up, some girls stopped posting, others went independent, and Iris and Isabella stayed with the agency with newer girls as part of their group.
