Let me share the screenshot of the official mail I received as a badge of Top Writer 2018, it says “in recognition of your highly valued contribution to Quora over last year”

I always thought that this badge was based on someone's popularity based on number of followers,upvotes,views,comments etc.

*My follower counts increased from 155 to 165 after I received this badge.*
