Your on point. People have abuse their voting powers, this action of self up voting will destroy the system sooner or leter, those who write good content doesn't make money anymore because of self up voting, people cast their vote on their comments instead of the content written. I have two articles I just posted but only few upvote. But I spent days cracking my brain on what to write but at the end of the day I won't get reasonable up vote. If this madness continue, people will stop writing article and just up voting their comments. Your solution to this which is to unfollow such people is very okay . also they should reduce the reputation of such people to 10 or even block their account. I believed that the idea for this blogging is to encourage people to write good content and make money from it, in other to encourage them to write more. Nice article. Upvoted. Keep it coming.
