If it's true that Pixiv is no longer going to be allowing artwork which portrays *fictional and non-existent* characters which are "minors" or in "non-consensual" situations, I will consider closing my account and never returning to the platform. They will also lose me as a premium paying customer.
Censorship of things which don't even exist in reality.
If people can't handle that, their minds have already become dangerous enough to not be able to distinguish between fiction and reality, making them a problem to humanity. The artwork is not the issue here, the fallacious and conditioned cultist mindset of the offended parties is.
