i have a few referred members, i think mine are from youtube and quora! that is the only thing i can think of. i dont have a kofi here but on my YT i do and dont advertise it and have made 0 on it.. but i have people from YT always emailing me and send them a consultation price and they just say but we are friends.. so i am kind of like you i dont advertise.. do my thing, and move on...
