Yep add fans pressure to this, but if she is doing only for money i beleive she should stop, she probably earned a lot but if she likes doing i think she would just pause for some time and return later.
It's a vicious cycle. A lot of cosplay creators get into patreon/onlyfans modeling because so many people ask for it and it's a good way to fund an expensive hobby like cosplay.
But after a while it goes the other way around, where you're doing cosplay to make content for the platform and not using the platform to help make cosplay. It's especially rough when you're a chubby girl or strictly tease/nonnude. Most of your fans are supportive, but the ones that aren't are BRUTAL and eventually it's just not fun anymore.
I don't follow her social media specifically so I don't know if she's reaching a breaking point or just going through a rough patch temporarily. Either way, I hope it gets better and I'd totally support taking time away if that's what she needs to do.
