Steemit is sold as a place where the best content will rise to the top. But if you can buy a massive vote for yourself to increase your reputation and the posts visibility as well as the amount it earns, that has to be against the concept of ‘the best content being rewarded’. I see no real justification for bots. Popular posters have hundreds of dollars worth of upvotes within seconds of posting when no one has read the post. Surely that shouldn’t happen?
