Hi @Shohana1, there are actually no specific requirements for becoming a best user.
We always try to reward users who actively participate in the activities of the Italian community, by entering our contests, sharing quality posts, interacting with other members through comments always of quality and related to the topic of the post. In short, how much users dedicate themselves to be an integral part of our community.
I hope I have been helpful and good luck with the next best user contests. 😜
