If you're getting that feeling due to your HN account, it's because you're shadowbanned. Only people with showdead will see your comments. It's actually really impressive how you've managed to write hundreds of comments to void for the last half a year without picking up on the hint.

There's a good chance you're not picking up on hints IRL either. Maybe ask a blunt friend what they think of you? The industry is small and people talk.
