I actually asked her about this on DMs, and she replied, which surprised me.
According to her, there's no overlap between Onlyfans and Patreon (Fansly doesn't even factor for her, which might indicate a lot of things).
Patreon audiences want cosplays.
Onlyfans audiences want thot shit.
Patreon audiences complain when she puts out "low quality" stuff. Onlyfans audiences complain when she sells "expensive" stuff. She sells stuff for 100 bucks+ on her OF, just so you know...
So yeah. According to her, her metrics say she has two fanbases and she apparently tries to cater to them both, She should nuke her patreon and go nude already, if you ask me.
