Imagine if dating apps paid you to keep your profile active even if you have no interest in meeting anyone. They pay you $5/month per match with a minimum of 5 messages before ghosting. It keeps lonely men on the platform. For some people, OnlyFans chat is no different.
There should be clear disclosures that there is potential the other account is outsourced to a different person, or a LLM.
I'm having trouble finding it now, but I recall there being a rumor that the Bumble CEO was fired for permitting fake accounts to exist, so that usage appeared high. I think it had to do with allowing virtual phone numbers
EDIT: Wow.... there are a lot people in this thread pushing back on the parent comment suggesting outsourced model chats are immoral, or not an ethical way to make a living.
