all good points
I'll add one more thing; whales and witnesses need to be more aggressive and decisive the next time a known bad actor makes play. @justinccp was such for the shenanigans he had already pulled. A preemptive strike was justified, but we as a community gave him the benefit of the doubt, and he strangled the life out the platform with it.
Furthermore, the sale of STEEM that had been promised to the community as a whole gave additional justification for zeroing him out.
