On one hand, I can appreciate you doing some work. On the other hand, an actual fundraiser was my first result upon googling "Fred Hampton gravestone fundraiser", which is far quicker than asking ChatGPT would have been. You put in extra effort for worse results (your link has nothing to do with his grave, and instead seeks landmark status for his home). So I believe "do less next time" is a pretty apt response.
Edit: I've emboldened a portion of this comment to emphasize it more. I was not intending to start a whole argument over this. It was meant to be a simple criticism of the method.
I have no issue with ChatGPT, I simply dislike when people rely on it as their first and only source and give unhelpful answers because of it. (Edit: Not to mention ChatGPT can be quite dangerous when used this way. Its a bad habit that shouldn't be encouraged.)
And I wouldn't say I put in more effort in my response considering the amount of caveats they added in theirs about how they asked chatgpt and have no idea if its real. Our responses were similar in length, mine is just all one paragraph and so looks bigger. If I had responded to the original question, I would have just dropped a link and that would have been the end of it.
