Which observations should be flagged?

Ordinarily I’d agree, but I said above, the DQA on that is a warzone. I have a feeling any votes to turn it casual will be swiftly noticed and countered.
And there’s not much point in trying to overturn it, since staff hadn’t already weighed in via the flag comments to say it is fine.

Though it is odd that some people are voting in favor of “Recent evidence of an organism” in the DQA.
I thought the cutoff for recent was around 100 years, and that is dated 1870.
