in a decentralized system it is up to the other users to do something about fraud and abuse. that is the power of the voting system. if its a serious problem then users should organize and make it unappealing to the abusers. that can be done through flagging and down voting. but remember this is the internet and it will resist any attempts at censorship or moderation. you currently coexist with all the copyright infringers and fake newsers online now so why not in this community?
i get its because they are getting rewards that other minnows work hard for. but if thats the case one could fork steemit and start a new platform which if based on the same technology will also catch on as users get dissatisfied with the increasingly saturated steemit platform.
Well said.
