I respectfully disagree in that voting for accounts actively sybil attacking the chain dramatically decreases the security of the chain as far as DPoS is designed. Witnesses who understand this should not support sock puppets.
That said, I don't agree with how this was decided. I tried to change minds and said it would be a black spot on the beginning of this chain. Unfortunately I was unable to convince those involved to take a different approach and just focus on the Steemit ninja-mined stake.
