I think a professional headline would usually just lack the comma there. Headlines typically have weird phrasing (due to their terseness), but they’re generally still grammatically sound.
I think “HackerNews owner hacked” would be a headline, rather than “HackerNews owner, hacked”.
“Have I Been Pwned owner pwned” seems to be on par with “Headline English” to me
This isn’t using the meme effectively.
“Nobody wants to work anymore for you” would’ve been closer
