I understand your frustration. The way blocking and display currently work may indeed be a bit rough around the edges, and we are working on improving those aspects bit by bit.
I completely understand your feeling of "I just want to enjoy this by myself." However, please let me clarify one thing. This site is more like a public square in a city than a toy you play with at home. This is especially true since it’s a free site that doesn't even require a login. Furthermore, because users from multiple countries visit, that "square" becomes even broader.
Therefore, there are inevitably things that might be okay to play with at home but change when you bring them into a public square.
As for the specific rules:
・All photorealistic Sensitive Content is prohibited.
・Sensitive Content involving characters that clearly appear to be minors, whether anime or photorealistic, is strictly prohibited.
・Anime-style R18 content cannot be generated. R15 content can be generated, but it cannot currently be posted to the Gallery.
Since these rules are a combination of regulations from multiple countries, they might seem a bit strict.
However, even though these are the rules, the actual judgment relies heavily on automated AI detection, so things that should be prohibited sometimes get through, and conversely, images that shouldn't be a problem sometimes get blocked. We are fine-tuning this as well, and our goal remains in line with the rules mentioned above.
