The comment above is a result of a script that runs on all posts in english with more than 500 words in a handful of categories. Admittedly the sentiment analysis is not that complicated. It basically uses the nltk library to categorize words and groups of words as positive or negative on a scale of -1 to 1. Your post just has more negative words in it than 99% of posts.
I apologize if it looks like my script (or bot, if you will) looks like it is trying to invalidate your post. On the contrary, I was hoping that by quantifying the positivity and negativity score, the sentiment scores would be objective and not have that affect. The only goal of these automated comments is to give you insight into your posts and help you better understand the content you are creating.
I also hope that readers don't see 'negative' and assume that that means your post is not of substance. If you believe that that is the case, it likely means I could use more descriptive language in the comments of these posts to give readers and content creators a better understanding of what the bot is for.
