Sure last year but what about all the money she made before then, 40-50k a month is ~600k a year she's most likely a millionaire, doesn't need to work another day in her life if she's smart with her money and doesn't blow it all. She just doesn't need to do this anymore she's set and as others have pointed out her content was more of a softcore porn than anything and will attract a loud minority of creeps who scare people especially because she did GFE type stuff that'll make lonely creeps feel attached to her as if she's their GF
I remember people talking the internet once about wanting her address and stuff like that, she or people connected to her end up reading that sort of thing too and if she's already a millionaire why risk it? Why not just disappear into anonymity again. What's the downside? She keeps the Patreon and in the odd case she might for some reason need money again she'll make a couple of vids get everyone excited and going mental and then dissapear again like Belle Delphine but once they've reached a certain financial stability you cannot expect them to keep producing steady content, you wouldn't be doing it either.
And i really doubt she's living off her BF as others have stated if anything her BF is living off of her lol people have no perception of how much damn money a million dollars is if you're living a relatively normal person life and don't dive into ridiculous rich people luxuries you'll never need to work again.
I don't really mourn Aftyn's departure, e-girls come and go that's always bound to happen, i mourn that no other girls watch her stuff and learn from her playbook, she was an absolute master of mixing ASMR, GFE and softcore porn, Maimy is i think the closest and a lot of Aftyn's fans migrated to her over time but she's still nowhere near as good
