Asher had a post about the Haejin the other day talking about his effect in the platform
https://steemit.com/steem/@abh12345/the-haejin-effect
In one of the comments that I left there someone replied that there was an account that was monitoring how effective the TAs of Haejin was and it was this account https://steemit.com/@truthtrader
I admit I was a follower of Haejin at the start in Twitter but never in Steemit because the amount he is getting is just crazy and he just uses it as a cash cow.
I remember Anomadsoul even tried to reason with the guy to at least lessen the self voting.
I don't think that self voting is bad by itself anything above 5% though I have to shake my head and according to his latest data in steemocean he was at 92% and the rest are downvotes to his detractors.
