RE: Stopping @haejin Will Require A Combined Community Effort!
If you see so few users flagging @heajin maybe there are good reasons. Is everyone too lazy or scared of him?
Delegating to a bot will cost you 7 day of lost steempower when you remove delegation. For this reason I don't see this initiative as the most effective.
If you want to protect people doing bad investment following his predictions then you should make a notice on all his post and upvote it so it's the first comment people see.
You can count on support from whales to resolve unjustified flag wars, if you feel like @heajin post are more over-valued than the majority of Steem content then flag them and don't be scared of reprisals.
