A summary of the events:
1. The Vtuber in question tried to lecture people "not to draw NSFW of her", she did not qualify it by saying full-on offbrand until much later when her posts did not turn out the way she wanted.
2. Many accounts outlined the initial hypocrisy of her statement as she repeatedly reposts NSFW art of herself, and even did so immediately after that post you are referencing.
3. One of the accounts, ChibiReviews also mentioned her hypocrisy - she subsequently responded by mocking him over the fact his ex-fiancee cheated on him.
4. This further added to her hypocrisy as she once lectured people not to "mock others when they are at their lowest point in life" and called it toxic - especially so when she herself talked about a similar abusive relationship she had. She chose however to do it against someone else, solely because she didn't like him.
5. Add to that fact as well, this Vtuber did what Quartering did - alleged false DMCA claimed a few videos that were critical of her, so the videos get taken down. THIS is the reason why I am unhappy with Deme the most, if she can do this to one person, she can do it to ANYONE who crosses her.
6. Her reaction to people finding out her hypocrisy and her decision to mock someone's personal life relationship trauma - is to link to a 24/7 stream account that falsely claims she is "live" - and she admits it is "for Twitter engagement"...again despite the fact that she calls out other for doing exactly that.
So no, she did not get "mass hate" for "asking people to draw p*rn" of her - she is getting called out for her combined actions of hypocrisy, and abusing Youtube's flagging system to perform false-flagging takedown of videos that criticised her. The internet has the least amount of mercy for people caught being two-faces who choose to double and triple-down despite being found out.
You claim you do not get much Vtuber "community" stuff in your life, fair enough you don't have to.
My advice however when you decide you DO want to give an opinion on it regardless of how little you know of the current situation, at least have some due diligence to know a little bit more before you give the opinion.
So glad to not get much vtuber community stuff in my life these days because what do you mean this vtuber is getting mass hate for…asking people not to draw p*rn of them?
I don’t care if they make lewd joke, that is a very normal and reasonable boundary any streamer can make
