Ask HN: Why was my 'Show HN' submission flagged?

Hi, I just submitted a tool I created that estimates COVID-19 risks based on best scientific data available, while providing the detailed sources and explanations for each calculation [1][2].

It got quite a few upvotes in the first few minutes and some constructive comments. However, it seems the someone decided that it should not be displayed and it is now marked as flagged.

Could you explain why?
