BitScreener has what is called the Content verifier module. The module uses the internal database of BitScreener and outside data to verify the source and originality of every content People post on Bitscreener. This is the first step, then they are those who are known as Reviewers, these reviewers are carefully picked and what they do is to review contents people create. This is where BitScreener differs from say Steemit, contents on BitScreener can be rejected or accepted in which case points will be awarded based on the quality of work with less point awarded to the rejected article.
