Yeah I have to agree. It would be one thing if the poster were a known member of the HN community, or any adjacent community, but it's a brand new account. I don't think this kind of posting is sustainable.
I would genuinely like to know more about how this person is connected to this community or how they discovered it and what they thought this community in particular could assist with. Could you address that OP?
I was about to post exactly the same question. Very interested why he chose this community.
