GPT-3 seems to be skilled enough to write forum comments that aren't easy to identify as spam. While OpenAI reduces the access to it's API it will likely don't take that long till other companies develop similar API's that are more freely available. While this isn't the traditional AI safety question, it does seem like it starts to become a significant safety question.
I'd say that it wasn't stereotyping, but saying "poor Indian" instead of "poor person" makes it seem unnecessarily racialized.
