LoverFans review
LoverFans offers paid subscriptions to individual profiles alongside posts with their own price. Its collaboration rules distinguish between a creator already on the platform and someone joining an upload from outside it.
Following and paying for a profile
The platform’s own profile separates free, subscription and pay-per-view posts. The billing guide says subscriptions renew by default and shows where to turn that off for a creator. On Bikini Fanatics, premium unlocks use a separate token balance. On LoverFans the first question is whether the listing belongs to the subscription or has its own price.
Adding an authorized person
The creator application requires a government-issued ID and a matching selfie. For a collaboration with another approved creator, both accounts follow each other and the other creator accepts the authorization request. For an outside participant, the uploader adds an Authorized Person and attaches supporting documentation. The publication guide also requires explicit consent and the necessary permissions for jointly authored work.

Anabel’s take
I'd use the post filters to see how much of a profile is actually in the subscription before leaving renewal on. If a profile mainly sells posts one at a time, I'd judge those purchases individually.
