I actually wonder why not more whales take action on this. They are invested in steem as well and if scammers do let the system implode, they will loose the most.
So what is the problem? Are there too many scammers? Are the whales on different sides on this topic? Are downvotes too weak?
I think the biggest reason is when you're flagging you're not able to curate. I don't think a lot of people are interested in making $0.00 for weeks to shut him down. We will all have zero if it collapses though
