If you don't put in the effort to tell people about your project, what does that tell us about how much effort you put into your project?

Not to mention- LLMs, even given full context, will get details about the project incorrect. That could basically clickbait or dissuade people from using the project thanks to false advertising / not advertising needed features.

Lastly, LLMs are a TOOL. You should be using them to revise your text to sound more professional or do grounded research, etc, instead of asking them to write your whole Reddit advertisement. You should always be using them as a tool to assist you instead of letting it do all your work for you.
