Right, I can answer this because I nearly ended up doing this. She send a series of "texts" via Fansly (each just in reality a content bundle box thing" each containing a single word, which when you open them you have to reply in the DM bit. The first is relatively cheap, but surprise surprise the keep getting more expensive. the message eventually spell out something like "I" "Bombardier" "Promise" "Not" "To" Leak" "Bonnie Blues" "Content" at which point I dipped out already £600 in the hole. after a bit of argie-bargie she admitted the total cost would be around the £1500 mark, I kid you not. She did supply the film I wanted after a bit of toing and froing, but paying £600 for a 15 minute movie still sticks in my throat. I reported the scam, because that's what it is, to Fansly but I don't think they give a horses arse.
So that's what it will cost you to get on the accepted list. £1500. do it at your peril
