What is happening? So much cencorship on artistic creation in AI?

"I am facing substantial difficulty in generating AI videos due to what appears to be an overly restrictive content filter regarding artistic prompts. Specifically, prompts that include unique or non-standard aesthetic descriptions are frequently rejected with the generic message 'Cannot create the video.' The accompanying explanations for these failures are often vague and insufficient. I require clarity and accountability regarding these restrictions, as they impede my legitimate artistic liberty on your platform."
