Did your friend fall 'in limerence' with her, spend money he could ill afford? I'm not mocking him cus it happened to me too, it's easily done, and it's taken me a long time to break free and come to my senses. I think the reason why most people go on OF, even if they struggle to admit it, is because they're looking for more than just tits n ass, since you can easily get that for free. They're looking for human connection, to chat to a "real" girl they find attractive, to fulfil basic emotional needs I think we all have, things that might be lacking in our lives for various reasons. It's just a theory, based on personal experience, but why else would you pay for it, when you can quite easily goon for free elsewhere?
Like your mate you describe, we spoke multiple times every day, she would often be the first to text and it felt good, you know? It felt "real", like she genuinely liked me. And maybe she did in some ways—why else would you spend so much time with someone?–but I also spent a lot of money on her, so who knows? And I'm definitely not rich or "retarded" (horrendous word btw). Even tho I was spending a lot (for me) it's never enough for girls like her, they always want more, and they'll make you feel inadequate when you can't keep spending indefinitely. She liked to tell me how guys would drop 3k on her on Spoil Me for nothing. It's really obscene how much these girls are earning compared to the general population and for what? Her Spoil Me page really highlighted this for me. To me, it's the sort of money you'd spend on a girlfriend you're really serious about or your wife, it totally baffles me why anyone would spend that sort of money on an e-thot they're realistically never gonna meet. WTF are they thinking, has the world gone completely insane!?
I talk about this to save other people from potentially getting sucked into the trap and getting caught in the web of lies. It isn't real, however much you'd like to hope it is. I don't think I'm a fool either, I'm just human. And you can think or say what you like about me anyway cus I don't give a fuck.
Her content isn't even worth the money either. She consistently overpromises and underdelivers, she's a scam artist and a fraudster preying on human weakness, nothing more. ("Weakness" is the wrong word too, since we're just talking about normal human unmet needs and desires) Her content is soft and never quite goes far enough. It's repetitive, gets boring after a while, and is often poor quality, like loads of basically the same pics, or screen grabs of videos which are grainy and low quality rather than high res photos with decent lighting. Her sexting ain't that great either, her English isn't brilliant so you get the impression she isn't following sometimes (although, it's a lot better than my Ukrainian/Russian!), she rarely, if ever, says anything of any depth or worth, and she often avoids your questions to the point where you don't see the point in asking any.
My advice to anyone would be to avoid this basic bitch like the plague, don't fall for her bullshit, and don't waste your hard-earned cash on her cus she ain't worth it and she doesn't value you. Focus on improving yourself and spending time and money on something real instead, that's gonna bring you long lasting happiness. OF is bullshit, and you're better off without it, IMHO.
