My friend has an onlyfans

I had this friend for maybe five years and we broke up months ago over something else, I used to see her posting really revealing photos on social media and I see her with a new guy every time, but she never introduced me to a single boyfriend of hers, me and my other friend we used to wonder how come she's able to afford all this luxury stuff without working full time ? One day I said to her something about only fans I think I said it was bad or like prostitution and she said oh no it's okay job I also have only fans 🤣 I was thinking what the hell is it for? This was years ago when it first started , I only remembered it due to another conversation I had regarding a woman who found out her husband is subscribed to multiple accounts on only fans and it made me wonder what if my husband is subscribed to one? He is always on that computer doing god knows what.
