This "blacklist" comes from James O'Keefe's Project Veritas. They have a long history of staged "expose"s around the current Republican "bad guy of the day"; ACORN, voter fraud, etc. Regardless of whether this is legit, I'm surprised it showed up on HN.
It changes the likelihood of the veracity of the document. If HN has done some sort of vetting, great. But there is no reason to take at face value anything that comes from Veritas.
A discussion on censorship is a great thing to have. Just not starting with this guy.
...As opposed to all of the other media outlets with their stellar records of truth-telling.
The "publication of record" ship has sailed and we're left with competing agendas and increased need for personal vetting, which many have done on this leak--a fact which is easily searchable.
