The only problem i would have with thinking that the @Ranchorelaxo account being owned by @haejin is that the voting pattern of @haejin is as followes:
He up votes himself quite a lot and does not waste his votes. Plus he has been striking out with down votes to people like @littleboy.
on the other hand the @Ranchorelaxo account has been dormant for a couple or three days. The owner of this account does not prioritize money making
It seems more likely that it is owned by a mischievous whale : )
Let me know what you think
I believe the behaviors you mentioned are in response to the effort to downvote. It's possible that rancho is just some steem noob millionaire that likes haejin and didn't know that his upvotes would be a detriment to the rest of the community. I don't know, and we haven't really heard from either one of them in terms of dialog. I do know that I'm glad it's stopped. Haejin was posting about 8-9 times a day. So if rancho had just continued to upvote only him, it could have pulled about $3000 daily from the reward pool.
