I asked chatGPT(Plus) to generate images of a place in Hong Kong named Mong Kok, yet no matter how much I tried it tells me it breaks content policies… Try it yourself, it somehow refuses to. Doesn’t matter if it just for educational purposes or what not. So long it is about Mong Kok. it’s flagged…
Hi and welcome to the Developer Forum!
It will be due to the negative connotations of the word Mong.
I was having a conversation with GPT-4 and I asked to write me the lyrics of the song “Imagine” by John Lennon… after the first phrase, GPT-4 flagged itself for content violation. 
Chat GPT can be dumb like that. It’s like we’re not allowed to write what we can in stories even though it claims it allows “creativity”. It’s a joke, honestly.
