Porn and OF are not similar. Porn is more of a job and OF a lifestyle
Sure, it is advertised as something one does as "a lifestyle", but when the model works for a professional studio with metrics to reach and gig workers chatting with customers while pretending to be her [1], how is that not a job? And more important, how do you know that the model on screen is doing what (s)he's doing because of their "lifestyle" and not because they are behind on their weekly numbers and may otherwise lose their spot in the agency's rotation?
Riley Reid/agency models go from job to job as an IC and gets a check from the company via simps dedicated to a certain website.
The former is a much easier sell/explain and a bit easier to justify to puritans. It’s all very samey but different.
They're both still porn and they're both definitely a lifestyle. One does not merely "do porn".
