The trouble is that only selected messages are interfered with. Zullo got several emails from me and responded to them. It was just that particular email talking about how HI’s “verification” actually strongly supports Obama’s BC being legally invalid that he didn’t get.
And similarly, I received some emails from a couple people but just not specific ones that I only found out about because they sent follow-up emails expecting that I had gotten their first emails.
So a generic test doesn’t diagnose this problem; they let generic emails get through. It’s just specific ones they block. The critical ones.
