I literally had never heard of this before. I don't check HN every single day.
It's extremely reasonable to ask for a link, very easy to include one when making a claim, and attacking someone for asking for evidence is extremely anti-intellectual independent of the level of effort required.
(n.b. that doesn't excuse the hostile way that they asked for proof - "Let's all just believe this baseless assertion shall we")
They were pointing out the lack of evidence on my part. I agree it was rude but I don't think it's helpful to start calling it misinformation with no evidence. They had a valid point that not everybody Just Knows already, hence why I did reply with a link. I don't think it's constructive to jab much more than I did in that reply.
