Reputation is one of the biggest measures to understand the power of the blogger (artist, writer, poet etc.). Also, it is exponentially difficult to rise from 60 to 70. A blogger with 60 has to create quality blogs to increase his reputation. However, there is a issue with upvote bot or whale bot, that can help to increase reputation. Some cases, reputation may not represent real quality since someone with huge SP can use selfvote or, buy whale votes to increase reputation significantly. However, beyond 65 reputation that mechanism may not help. Thanks again for explain reputation in easy and visual terms.
