Earlier quoted context omitted.
What was your experience? I haven't been able to find where we interacted with you.
Of course not. I'm not insane and so I didn't continue using a shadow banned account.
You said we weren't willing to hear you out, but that seems unlikely to me. People sometimes come to HN with stories of how badly we've mistreated them, but rarely provide links or enough information to let readers make up their own minds. Mostly these stories leave out important details about how the account had behaved and how we interacted with them. But we do make mistakes—moderation is guesswork, and we guess wrong sometimes. If there's a chance of that, I'd like to know what we did so we can correct it.
We only use shadowbanning when accounts are new and show evidence of spamming or trolling, or unless there's evidence that the user has been serially creating accounts to abuse HN. It's possible we got it wrong in your case, but again, we can't correct mistakes if people won't tell us about them.
