I've never had a problem on OF. I do use dual factor authentication for everything that supports it though. Some girls put decent content on OF that don't require more money, but most seem to use it to provide previews to buy their content. I used to buy a lot of premium stuff from MFC and CB girls, but they almost all seem to offer discounts for buying those same videos through OF. OF only takes 20% from the girls so it ends up being a better deal for them. Honestly, though, if you are not a whale then OF and Patreon just aren't for you.
