RE: What info would you want to see here?
From my experience as a curator, I can say that a word count would be very helpful. No, not because the curators only support posts with more than 300 words. This is already in the past. It's just that if the post is not about visual art and it only contains, say, 10 words, it will save the curator time and he won't even review it. Curators are also people and they mostly always lack time 😄.
Information about bot voting will also be invaluable for optimizing the work of curators.
One of the curators' tasks is to distribute votes as widely as possible, including by geography of authors. However, I don't think any extension is capable of telling which country the author is from. But maybe you can indicate in which language the post is? It will probably be possible to do this at later stages with the involvement of AI.
I also thought about location and language. There are JavaScript language libraries that can report back on the text's language, but I'm not sure if that can be incorporated into a browser extension. I'll look into it, but I have a feeling that it might be challenging in this context.
