With traditional adult entertainment, creators are aware of the social ramifications (e.g., social stigma, familial ostracism, difficulty dealing with the future, and so on), and there is a decent theoretical economic framework to measure that.
I am not sure if there's the same this new army of "civilians" joining OF, let alone the additional toll it will take on the creators in terms of social ostracism, future prospects, future opportunities, and mental health.
A few decades ago, there weren't that many "productions", performers were much fewer and some porn performers name were known by anyone, regardless if you had seen porn with them staring or not. A person getting out of the business and trying to make a new career would have a high chance of meeting people, especially men, in real life who might have seen at least one movie.
Nowadays pornhub and onlyfans are flooded by wannabee independent performers. Even the most addicted to porn can't possibly follow and keep track of more than a tiny subset of performers. So there is a good chance you can still have a career alongside it or switch from OF to a non sex related career easily.
I think the odds of getting recognized were a bit lower for me being a male, my peak live viewership was a little over 1k viewers. A video of me also got reposted and featured on PornHub gay and was able to accumulate ~100k views before I was able to get it taken down. There are still plenty of videos around that I wasn't able to get taken down but the big sites like PornHub respect DMCA takedown requests.
Regarding getting recognized, I think you are somewhat right but it likely still happens. I had 2 people recognize me in person, only 1 found my real name because they recognized me at my college graduation. Nothing came of it besides them trying to add me on FaceBook. I think for girls they would be more likely to get recognized if they are successful because they get a lot more viewers.
I was lucky that nobody that did recognize me posted anywhere about what my real name is since that would be a way to find the videos of me when people search my real name. I think that is probably the biggest risk with performing is that if that association happens, it would probably be hard to wipe that association from the internet. One way out of it for women though is that they could take their spouses last name when they get married, their new name wouldn't be associated with the old porn name.
I have told people in my life about that past job. It had no impact on any of those relationships and never really came up again. So if it did come up again, I don't think it would have much impact on my life. In my mind, sex work is real work and those who do it should not be shamed for doing it.
