At the same time authors are realizing this, they know that if say @bigaccount1 votes on their post there's no way @bigaccount2 or @mediumsizedaccount1 is going to add another vote on their post. What do you think this will encourage? Authors start to write content with a certain amount of effort just to be good enough to receive one of those big votes or they create several accounts so they can post more short posts daily to receive more votes from @bigaccount1 without them knowing - sockpuppets.
Anyone can already post as many posts as they could possibly want using a single account. There is no advantage to using sock puppet accounts for the purposes of being able to post a greater quantity of content. On the contrary, using several accounts for posting content comes at a distinct disadvantage. The alt accounts do not have any history of engagement, few to no followers, nor do they have any autovotes set on them. Far fewer curators, large or small will ever see the posts.
Also, isn't the whole point of rewarding content just that - rewarding content regardless of who authored it? In my opinion, one of the biggest problems of Hive in terms of content is the sheer lack of it. When I go to Quora to answer questions to ask them myself, I find an astonishing volume of content I could easily spend days or weeks engaging without exhausting interesting material. In contrast, Quello has such a dearth of content that there is very little to catch anybody's interest.
