Well until a human can verify.

Which likely is slow without a poke it's reasonable to base the decision on whats available.

That's just how reputation works.

It doesn't sound reasonable to me at all. Why would we think that the reasons google blacklists a domain would align perfectly with reasons a domain name would be suspended? In the end they don't seem to agree already since the domain was unsuspended. Who knows why it was blacklisted by google? Even the decision to unsuspend it looks arbitrary.

and anyone that trusts googles judgement here clearly needs a reputation of their own
