Revenue wise, you'll make a lot more money tailoring content to a small group of users who will pay for custom content / live cams etc than having any mass appeal with small donations. The large social media funnel is mostly there to get model's content out there to find the whales.
Context: I have a side business deploying chat LLMs for OnlyFans models for fans to "talk" to that's currently at 65k/MRR. It definitely helps with user retention, as models who chat to their fans will have a 2x or 3x spend rate per fan.
good job
How did you market this? Do you have a website for it?
Seems illegal, or at the very least a violation of OF's Terms of Service.
