My apologies, I just noticed a flood of these previously unrecognized domains which had a lot of "web chrome" around a central YouTube video. I shouldn't have included the language about flagging it, as that made my comment more negative than I intended it. I am slowly learning to pare down my HN comments to avoid that editorializing.
I'm not really seeing the issue. Complaining about how someone chooses to link to their own content seems silly tbh.
